Hager BB1816 4X4 US3 – Frequently Asked Questions

1) Is the Hager BB1816 hinge heavy enough for a commercial entry door, or is it residential only?
The BB1816 is a residential-duty hinge. Hager rates it Residential, and it conforms to the Light Weight requirements of ANSI A156.1 under certification A8134. For an apartment unit door, an interior passage door, or a light unit entry, that is the right spec. For a high-traffic commercial opening, a heavy or standard weight commercial hinge is the correct call: the McKinney TCA3386 is a heavy weight 4-1/2 by 4-1/2 full mortise hinge, and the Don-Jo BB74545 is a standard duty steel 4-1/2 by 4-1/2. Both are physically larger than a 4 by 4, so the door and frame prep has to suit.
2) The Hager BB1816 says assembled right hand. Can I use it on a left hand door?
Yes. Full mortise butt hinges like the BB1816 are non-handed in use, the leaves are identical and the hinge simply flips. Assembled right hand describes how the pin and knuckles are stacked out of the box, and with a removable pin you can drive the pin out and reset it from the other end so the pin still loads from the top. On a left hand door the hinge mounts and works exactly the same.
3) How many Hager BB1816 hinges do I need per door, and do they come with screws?
The BB1816 ships two hinges per pack with wood screws (3/4 X 9) included. A standard residential door hangs on three hinges, so plan on two packs per door and you will have one hinge spare, or order in pairs across a batch of doors. No separate fastener order is needed for wood jambs. On a hollow metal frame you supply machine screws, since the pack carries wood screws only.
4) I am standardizing hinges across an apartment building. Is a 4 x 4 Hager BB1816 the right size, or do I need 4-1/2?
For 1-3/8 inch interior doors, which is what most apartment bedroom, bath, and closet openings use, the 4 by 4 BB1816 is the standard size and what the existing prep will almost certainly be cut for. Unit entry doors are usually 1-3/4 inch and normally take a 4-1/2 by 4-1/2 hinge, so those openings need a different part, such as the Don-Jo BB74545 or the McKinney TCA2314, both 4-1/2 by 4-1/2 square corner 5 knuckle hinges. Measure one existing hinge in each door type before committing to a building-wide order, the two sizes are not interchangeable in the same mortise.
5) Can I use the Hager BB1816 where the door needs power for an electric lock?
No. The BB1816 is a plain steel ball bearing hinge with a steel pin and carries no wiring path through the barrel. To get power from the frame to the door through the hinge, use an electric through-wire hinge such as the ACSI 5BB1, a 5 knuckle ball bearing full mortise hinge sized 4-1/2 inch by 4-1/2 inch with a concealed electric through-wire of 4 conductors at 28 gauge, from the 1100 Series. Note the larger leaf size against the BB1816 at 4 inch by 4 inch, and plan the frame for a wire raceway at that hinge location.
6) I need a hinge that clears the opening for a wheelchair. Will the Hager BB1816 work?
No. The BB1816 is a conventional full mortise ball bearing hinge, so the open door leaf still sits in the doorway and eats into the clear width. To recover that width you need a swing clear hinge, which throws the door fully out of the opening when it swings. The BEST CB248 is a steel full mortise concealed bearing swing clear hinge cut for square edge doors, listed as medium duty in the Swing Clear Hinges series. Swing clear hinges use a different leaf geometry from a standard butt, so verify the frame prep and the door edge profile before swapping one in.
7) The BB1816 is a residential hinge. What should I use on a high traffic commercial opening instead?
The Hager BB1816 is specified for residential use with a 0.085 inch gauge steel leaf. For an opening that sees constant traffic or carries a heavy door, the McKinney TCA3386 is a square corner, 5 knuckle full mortise hinge in 4-1/2 inch by 4-1/2 inch rated heavy weight and heavy duty. The BEST CB223 is a heavy duty stainless steel concealed bearing hinge with pivot reinforcing, cut for beveled edge doors, and the Dormakaba CB199 is a heavy weight full mortise concealed bearing hinge from the Architectural Hinges series. All three step up in leaf size from 4 inch by 4 inch, so the frame prep has to be checked or reworked.
8) Can I take the door off without unscrewing the Hager BB1816 hinges from the frame?
Yes, the BB1816 uses a removable pin. Tap the pin up and out on all three hinges and the door lifts off the frame leaves, so painting, moving furniture, or swapping a door is a two minute job and the frame prep never gets disturbed. Worth knowing on an exterior opening: a removable pin is accessible from whichever side the hinge knuckles face, so on an outswing door it is exposed. Where that matters, specify a non-removable pin or a security stud hinge instead.
9) What finishes does the Hager BB1816 hinge come in, and which one matches satin nickel lever sets?
Three finishes are orderable on the 4 by 4 BB1816: 619 satin nickel, 605 bright brass, and 609 antique brass. For satin nickel lever sets and pulls, 619 is the direct match, it is the same BHMA finish number used across the lockset lines. 605 bright brass pairs with polished brass trim, and 609 antique brass with the darker aged brass look.
10) Is the Hager BB1816 steel hinge going to rust on an exterior or coastal door?
The BB1816 is steel with a steel pin, plated to the finish you order. On a protected interior or a covered entry it holds up. In a coastal, poolside, or otherwise wet exterior location, plated steel is the wrong substrate and stainless is what you want, the Don-Jo BB94545 is a stainless steel full mortise ball bearing hinge with square corners, or the Don-Jo BB84545 in brass. Both are 4-1/2 by 4-1/2, so confirm the mortise size before switching.
11) What is the gauge on the Hager BB1816, and will it hold a solid core door?
The leaf gauge is 0.085 inch. That is light weight territory per ANSI A156.1, which is what the BB1816 is built to, and it suits hollow core and typical residential solid core interior doors on three hinges. A heavy solid core or a wide door with a closer on it belongs on a heavier hinge, the Dormakaba CB199 and the BEST CB223 are both heavy duty full mortise options.
12) What is the difference between a ball bearing hinge like the BB1816 and a concealed bearing hinge?
The Hager BB1816 uses a ball bearing between the knuckles, which is the visible band you see in the barrel on a 5 knuckle hinge. A concealed bearing hinge hides the bearing inside the barrel so the knuckle stack reads as a plain butt hinge. The BEST 1900R is a steel full mortise concealed bearing standard weight hinge with a removable pin, medium duty, from the Architectural Hinges series, and the Stanley Security CB1960R is a full mortise concealed bearing standard weight hinge, also medium duty in that series. Both carry a bearing and both mortise into the door and frame; the choice between them and the BB1816 is appearance in the barrel and the duty level you need, not the mounting method.
13) I want a hinge that will not rust on an exterior or damp opening. What is the alternative to the steel BB1816?
The Hager BB1816 is steel with a steel pin. Where moisture is a concern, the Don-Jo BB94545 is a full mortise ball bearing hinge in stainless steel with a square corner, standard duty, and the Don-Jo BB84545 is a brass full mortise ball bearing hinge finished in satin chrome, also standard duty. Both are 4-1/2 inch by 4-1/2 inch, a larger leaf than the 4 inch by 4 inch BB1816, so the existing mortise has to be enlarged or the frame prepped new.
