Hager BB1741 3-1/2X3-1/2 US26 – Frequently Asked Questions

1) What sizes does the Hager BB1741 ball bearing hinge come in?
Two sizes: 3-1/2 x 3-1/2 inch and 4 x 4 inch. Those are the standard residential door sizes, 3-1/2 inch for lighter interior doors and 4 inch for entry doors or anything heavier. If your existing mortise is 4-1/2 x 4-1/2, which is the usual commercial size, the BB1741 won't drop in without recutting the jamb.
2) Do I need to order left hand and right hand versions of this hinge?
No. The BB1741 is reversible, so one hinge works on either handing. Square corners on both leaves, so you also don't pick a corner radius. That makes it easy to stock one part number across a building.
3) Will my existing door mortise fit this hinge, or do I need round corners?
The BB1741 has square corners, which means it suits a routed or chiseled square mortise. If your current hinges have radiused corners (typical of a template-routed prehung door), the square leaf won't seat in that pocket without squaring the corners with a chisel.
4) I need a 4-1/2 inch ball bearing hinge for a commercial door. What should I look at instead of the Hager BB1741?
The BB1741 tops out at 4 x 4 and is a residential-rated hinge, so it isn't the one. For a 4-1/2 x 4-1/2 square corner 5-knuckle ball bearing hinge, look at the Don-Jo BB74545 in steel, the BB84545 in brass, or the BB94545 in stainless. The McKinney TCA2314 and TCA2317 are also 4-1/2 x 4-1/2 square corner 5-knuckle standard duty hinges. For a heavy door on a closer, the McKinney TCA3386 is the heavy weight version in that same size.
5) The Hager BB1741 is rated residential. What should I use on a heavy commercial door instead?
The BB1741 carries a residential rating under ANSI A8114, which suits entry and interior doors in homes and multi-family units. For a heavy commercial leaf, look at heavy duty hinges such as the McKinney TCA3386, a heavy weight square corner 5-knuckle full mortise hinge at 4-1/2 by 4-1/2, or the Stanley Security CB199 full mortise concealed bearing heavy weight hinge. The BEST CB223 is a heavy duty stainless concealed bearing pivot reinforced hinge for beveled edge doors.
6) What is the closest equivalent to the Hager BB1741 if the door is prepped for 4-1/2 inch hinges?
The Hager BB1741 is built in 3-1/2 x 3-1/2 and 4 x 4 sizes, so it will not fill a 4-1/2 inch mortise. For that prep, the Don-Jo BB74545 is a steel full mortise ball bearing hinge in 4-1/2 x 4-1/2 with square corners and a 5-knuckle barrel, matching the BB1741's square corner, 5-knuckle geometry in the larger size. The McKinney TCA2314 is also a square corner, 5-knuckle full mortise hinge at 4-1/2 by 4-1/2.
7) Are screws included with the Hager BB1741 hinges?
Yes, wood screws ship with them: 3/4 inch x #9 flat head. That covers a wood door and wood jamb. If you're hanging into a hollow metal frame you'll need machine screws to match the frame's tapped holes instead, since those aren't part of the package.
8) Can I take a door off its hinges without unscrewing the leaves?
Yes. The BB1741 uses a removable pin, so you drive the pin up and out and lift the door off while both leaves stay screwed to the door and frame. Handy for painting, flooring, or moving appliances through a unit. Note that a removable pin is not a security pin, so on an outswing exterior door you want a non-removable or set-screw pin instead.
9) What is the difference between a ball bearing hinge like this and a plain bearing hinge?
Ball bearings sit between the knuckles and carry the door's weight on rolling elements rather than metal rubbing on metal. That means less friction, less squeak, and longer life on a heavy door or one with a closer on it. The BB1741 is a 5-knuckle ball bearing hinge. A plain bearing hinge costs less and is adequate on a light, low-traffic interior door that has no closer.
10) What finishes can I get the BB1741 in, and can I match the rest of my door hardware?
Nine finishes, and both sizes come in all of them: 605 bright brass, 606 satin brass, 609 antique brass, 619 satin nickel, 620 antique nickel, 625 bright chrome, 626 satin chrome, US10A antique bronze, and US10R dark bronze. 626 satin chrome and 605 bright brass are the two most common matches to builder lever and knob sets.
11) Do I buy these hinges individually or by the pair?
Both. The BB1741 is sold as a single piece or as a box of 2. A standard interior door takes three hinges, so figure two boxes plus a single per opening, or three singles. Taller or heavier doors may take four.
12) Does the Hager BB1741 support an electrified transfer for an access control door?
The BB1741 is a mechanical full mortise ball bearing hinge with a removable pin and no wire transfer. When the opening needs power carried from frame to door, the ACSI 5BB1 is a 5-knuckle ball bearing full mortise hinge at 4-1/2 x 4-1/2 with a concealed electric through-wire, 4 wire in 28 gauge. Keep the BB1741 for the remaining non-powered hinge positions on the same leaf.
13) What is the difference between the Hager BB1741 and a concealed bearing hinge like the BEST 1900R?
The BB1741 uses an exposed ball bearing between its five knuckles, so the bearing rings are visible in the barrel. The BEST 1900R is a steel full mortise standard weight hinge with concealed bearings and a removable pin, which hides the bearing inside the knuckle for a smooth barrel appearance. Both are removable pin designs, so either lets you lift the door without unscrewing the leaves. The Stanley Security CB1960R is another full mortise concealed bearing standard weight option.
14) Can I use a swing clear hinge in place of the Hager BB1741 to widen a doorway?
No, they are not interchangeable in function. The BB1741 is a standard full mortise ball bearing hinge that keeps the door within the frame opening. A swing clear hinge such as the BEST CB248, a steel full mortise concealed bearing swing clear hinge for square edge doors, throws the leaf clear of the opening to recover clear width for accessibility. The two have different leaf geometry, so plan the swing clear hinge in from the start rather than swapping it into an existing BB1741 prep.
15) I need a corrosion-resistant hinge instead of the steel Hager BB1741. What are my options?
The BB1741 is a steel hinge with a steel pin. Where you want a different substrate, the Don-Jo BB94545 is a stainless steel full mortise ball bearing hinge, 4-1/2 x 4-1/2 with square corners, and the Don-Jo BB84545 is a brass full mortise ball bearing hinge in the same 4-1/2 x 4-1/2 size in satin chrome. Both are larger than the BB1741's 3-1/2 and 4 inch sizes, so confirm the mortise before ordering.
16) I need a 4-1/2 by 4 inch hinge, not a square size. Is there an alternative to the Hager BB1741?
The BB1741 is offered in equal-leaf sizes, 3-1/2 x 3-1/2 and 4 x 4. When the frame rabbet calls for a narrower leaf, the Don-Jo BB74540 is a full mortise ball bearing hinge in 4-1/2 x 4 inch, satin chrome, standard duty. The narrower 4 inch dimension keeps the leaf off the stop on shallower frame reveals.
17) What hinge should I use if the door edge is beveled rather than square?
The Hager BB1741 is a square corner full mortise hinge. For a beveled edge door where the frame needs pivot reinforcement, the BEST CB223 is a heavy duty stainless steel concealed bearing pivot reinforced hinge made for beveled edge doors. If the edge is square and you still want pivot reinforcement, the BEST FBB212 is a steel ball bearing pivot reinforced hinge for square edge doors.
18) What is the difference between the McKinney TCA2314 and TCA2317 as alternatives to the Hager BB1741?
Both are square corner, 5-knuckle full mortise hinges at 4-1/2 by 4-1/2 in standard duty, which mirrors the BB1741's square corner 5-knuckle configuration one size range up. They are separate model numbers within the same square corner standard weight family, so match the exact TCA number to what is already hanging in the building when you are standardizing a fleet of openings.
