Grades: What The Number On The Box Means
Residential and commercial door hardware is graded against a published performance standard, and the grade is a summary of cycle testing and force testing rather than a marketing tier. Grade 3 is the entry level, tested to the lowest cycle count, and it is what fills the cheapest end of a big-box aisle. Grade 2 is the sensible residential exterior standard. Grade 1 is built for commercial traffic and heavier abuse.
The number that matters for a house is durability over years, not survival of one dramatic attack. A Grade 3 knob on a back door that opens four times a day may be perfectly adequate for a decade. The same knob on a rental's front door, operated by strangers with sandy hands during turnover season, is a wear item that will fail in a fraction of that. Grade should be chosen per opening, based on traffic, not bought uniformly for the whole house.
Finish Is A Durability Specification, Not A Colour
Finish codes describe both the appearance and how it was applied, and the application method is what decides survival here. Lacquered brass is a clear coat over a bright plating; once the lacquer is breached anywhere, salt air gets underneath and the plating lifts from the inside out. Painted and powder finishes chip at the edges where keys and rings strike them, and corrosion starts at the chip.
The finishes that hold up on a Gulf-facing door are physical vapour deposition, which bonds an extremely hard layer at the molecular level, and solid stainless — ideally a marine-grade alloy on the most exposed openings. They cost more up front and they are the only ones that still look like themselves after a few seasons of onshore wind. On sheltered interior doors, none of this matters and you can buy on appearance alone.
Handing: The Measurement People Get Wrong Most Often
Handing describes which side the hinges are on and which way the door swings, and it is determined standing on the outside of the door — the secure side. Hinges on the left with the door swinging away from you is one hand; hinges on the right swinging away is the other; a door swinging toward you is a reverse of each. Lever handles and mortise locks are handed; most residential cylindrical knobs and levers are reversible in the field.
It is worth getting right before ordering, because a handed lock in the wrong hand is a return rather than an adjustment. When in doubt, stand outside, note which side the hinge knuckles are on, and note which way the door moves. That one sentence, given over the phone, prevents most wrong-hardware visits.
Backset, Bore And Door Thickness
Three numbers decide whether a lock will physically mount. Backset is the distance from the door edge to the centre of the large hole, and residential doors are prepared at one of two standard distances. Bore is the diameter of that large hole, with a smaller cross bore through the edge for the latch. Door thickness matters because standard hardware covers a range and anything thicker — a heavy custom exterior slab, for example — needs an extended kit.
Measure before buying. A tape across the door edge to the centre of the existing hole gives you backset. A measurement across the face hole gives you bore. A measurement of the door edge gives thickness. Three numbers, two minutes, and it eliminates the most common reason a homeowner ends up making a second trip.
Function: What The Opening Needs To Do
Hardware function is a specification separate from grade and finish. An entry set locks from outside with a key and from inside with a thumbturn. A passage set has no lock at all and is for hallways and closets. A privacy set has a simple interior lock with an emergency release and belongs on bathrooms and bedrooms. A storeroom function stays locked outside and always opens from within.
Choosing by function rather than by picture avoids the two classic residential mistakes: a privacy set on a door that needed a key, and a keyed set on an interior door where somebody will eventually be shut in behind it. On a rental, function choice also decides how many things a guest can accidentally lock themselves out of.
Double-Cylinder Deadbolts And Getting Out In A Fire
A double-cylinder deadbolt takes a key on both sides, and homeowners ask about them because of glass beside the door. The trade-off is severe: in a fire or any emergency, everyone inside needs a key to get out of their own house, in the dark, possibly in smoke. Residential codes restrict where these can be used precisely for that reason, and they are the wrong default for a family home.
The better answers to glass near a lock are addressing the glass and the frame rather than removing your own exit. Laminated or security film glazing, a sidelight that is not within reach of the thumbturn, and a properly reinforced strike all reduce the risk without making egress conditional on finding a key. If a door genuinely requires a double cylinder, it needs to be a considered decision with the escape plan discussed alongside it.
Keyways, Keying Alike, And Not Painting Yourself Into A Corner
Every lock brand uses a keyway profile, and only locks sharing a compatible keyway family can be operated by one key. This is the constraint that decides whether a house can be keyed alike, and it is why mixing three brands across five doors creates a problem that only becomes visible after everything is installed. Where profiles differ, a cylinder swap on the odd door out usually resolves it.
Decide the keying plan before hardware is bought. One key for all exterior doors is the common request. A small master arrangement — one key that opens everything, plus limited keys for a cleaner, a guest suite or a workshop — has to be planned as a set, because it changes how each cylinder is pinned. Retro-fitting that plan afterwards means a second visit to every door.
What Actually Fails First, By Component
Springs and small internal parts go first in this climate, which is why coastal hardware usually dies by becoming stiff rather than by snapping. After that come the finishes at the wear points — around the keyway, on the underside of a lever where hands catch it, on the edge of an escutcheon. Next are latch springs, which weaken until the latch no longer snaps out fully and the door starts requiring a push.
Bodies and bolts are last, and they are the parts people replace hardware to get. That inversion is why servicing is so often the correct answer: the expensive components are fine and the cheap components are the ones that failed. Knowing the order also tells you what to look at during a routine check — the springs and the finish tell you what the next two years hold.
Hinges, Screws And The Parts Nobody Puts On A Shopping List
A door's security and its alignment are shared between the lock and the hinges, and hinges get almost no attention until a door starts dragging. Standard hinge screws are short and land in the jamb trim. Replacing at least one screw per hinge with a long screw that reaches the framing behind pulls the door back into position and dramatically changes what happens when the door is struck.
Two more overlooked items belong on the list. A reinforced strike box, which gives the deadbolt a real pocket in the frame instead of a shallow hole in trim. And weatherstripping, which is a security component in an indirect way: as it compresses and ages, the door position changes and the bolt stops meeting the strike squarely.
Buying For A Rental Versus Buying For A Home
The calculation differs. A home's hardware is chosen for appearance and expected to be operated by people who know the door's quirks. A rental's hardware is operated by strangers with beach bags in one hand, and every quirk becomes a support call. That pushes a rental toward higher grade, simpler function, levers rather than knobs, and hardware whose behaviour is obvious to somebody who has never touched it before.
It also pushes toward consistency. Matching hardware across a portfolio means one set of spare parts, one keying plan and one set of instructions for cleaners. Buying whatever was on the shelf each time a lock failed is how a small portfolio ends up with six brands, four keyways and no spares that fit anything.
Warranty, Serviceability And Spare Parts
Two things separate hardware worth buying from hardware that is disposable. First, whether the manufacturer sells parts — latches, springs, cylinders, thumbturns — as replaceable items. Second, whether the cylinder can be removed and re-pinned rather than being sealed into the body. Hardware that can be serviced stays on the door through several key changes; hardware that cannot has to be thrown away to change a key.
Finish warranties are worth reading for a coastal property, because many exclude environments within a stated distance of salt water — which describes most of this area. That is not a reason to avoid a brand; it is a reason to buy the finish that does not need a warranty claim in the first place.
Bring Us The Door, Not The Box
The most useful thing a homeowner can do before buying anything is send a few photographs: the outside face of the door, the edge showing the existing latch, and the frame where the bolt lands. Those three images answer handing, backset, thickness, existing preparation and the state of the frame, which between them determine nearly every choice on this page.
From there the specification is short: grade per opening, finish per exposure, function per room, and a keying plan for the house. We can supply and fit the result, or tell you exactly what to buy if you would rather source it yourself. Either way the hardware that goes on the door is hardware that fits it.
Fitting Is Half The Product
New hardware screwed onto a door that is out of alignment performs like the old hardware did, because the failure was never in the lock. Correct fitting means the latch enters its strike cleanly, the deadbolt drops fully into a pocket that is deep enough for its full projection, the door closes without being lifted or leaned on, and the hinge line carries the weight squarely.
That is why supply and fitting belong together. A visit that installs a lock without touching the strike, the hinges or the frame is a visit that has moved a problem rather than solved it — and it is the reason so many people conclude that new locks did not help.
