BEST BEST-F179WT-639-4x6 – Frequently Asked Questions

1) What does a wide throw hinge like the BEST F179WT actually do that a standard hinge won't?
A wide throw hinge sets the door further out from the frame when it swings, so the door clears the trim, a deep reveal, or a projecting casing instead of binding on it. That extra projection is what lets the door reach a full 180 degrees in a reveal condition. If your opening has no deep reveal, wrap trim, or obstruction beside the frame, you do not need wide throw and a standard full mortise hinge in the same weight class will do the job.
2) Is the BEST F179WT strong enough for a heavy commercial door, or do I need a heavy weight hinge?
The F179WT is a medium duty, plain bearing hinge. That suits normal commercial traffic on standard weight doors, offices, classrooms, back-of-house, retail. For a heavy or high frequency opening you want a bearing hinge in a heavier class: the Hager WTBB1168 is a heavy weight, ball bearing wide throw hinge with the same 5 knuckle build, so it is the direct step up if you need wide throw plus heavy duty. If you don't need wide throw, the McKinney TCA3386 is a heavy weight square corner 5 knuckle full mortise hinge.
3) Plain bearing or ball bearing hinge, which do I need for a commercial door?
Plain bearing, like the F179WT, is the right call on medium duty openings without a closer and with moderate traffic. Ball bearing is what you want under a door closer or on a high traffic opening, because the bearing carries the load instead of the knuckle faces wearing. If the opening has a closer, look at a ball bearing option such as the Don-Jo BB74545 in 4-1/2 x 4-1/2 steel, or for wide throw plus bearings, the Hager WTBB1168 in 4-1/2 x 6.
4) I need a wide throw hinge to clear casing but my door has a closer on it. What should I use?
Not the F179WT in that case. It is a plain bearing, medium duty hinge, and a closer puts continuous load on the hinge that a plain bearing does not handle well over time. The Hager WTBB1168 is the substitute to look at, wide throw, 4-1/2 x 6, heavy weight, ball bearing, 5 knuckles, so it gives you the same projection with the bearing and the weight class a closer needs.
5) If the door does not need extended clearance, what standard hinge matches the F179WT specification?
The Hager 1279 is a full mortise plain bearing commercial hinge with 5 knuckles, rated medium duty. That matches the BEST F179WT on bearing type, mortise type, knuckle count, and duty level. The difference is throw: the F179WT is built wide throw to push the door further out when open for 180 degree operation in a reveal, while the 1279 is a conventional commercial hinge. On an opening with no trim or reveal to clear, the 1279 is the direct plain bearing equivalent.
6) Will a Don-Jo BB74545 work in place of a BEST F179WT?
Not for the same purpose. The Don-Jo BB74545 is a 4-1/2 inch by 4-1/2 inch full mortise ball bearing hinge in steel with square corners and 5 knuckles, rated standard duty. It shares the full mortise format, steel construction, square corner style, and 5-knuckle count with the F179WT, but it is a square-leaf conventional hinge. The F179WT is a wide throw hinge, which sets the door out further when open than a conventional hinge. Swapping a conventional hinge onto a wide throw opening will not give the 180 degree clearance the wide throw was specified for.
7) What should I use instead of the BEST F179WT on a door that needs the full clear opening width, such as a healthcare corridor?
The Hager 1260 is a full mortise swing clear hinge with a 5-knuckle plain bearing design, rated heavy duty. A wide throw hinge like the F179WT moves the door out past trim so it can reach 180 degrees, but the door leaf still sits in the opening. A swing clear hinge carries the door entirely clear of the opening so the full clear width is available, which is the usual answer for wheelchair and gurney traffic. Both use a plain bearing 5-knuckle build, so the operation feel is the same; the geometry is what differs.
8) Can I run electrified access control through a BEST F179WT, or do I need a different hinge?
You need a different hinge. The F179WT is a plain bearing wide throw hinge with a removable pin and no wire path. The ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge, 4-1/2 inch by 4-1/2 inch, with concealed electric through-wire in a 4 wire, 28 gauge configuration. That is the one to specify when power has to cross from frame to door for an electrified lock or monitored opening. It is a conventional hinge, so if the opening also needs wide throw clearance, treat the power transfer and the throw as two separate requirements to confirm.
9) Can I take the door down without unscrewing the F179WT hinges?
Yes. The F179WT uses a removable pin, so you drive the pin out and lift the door off with the leaves still mortised into the door and frame. That matters for a property manager pulling a door to paint it or move furniture, and it means no re-drilling on reinstall. It also means the pin is removable from either side, so on an outswing door in a secure area you should be specifying a security stud or non-removable pin hinge instead.
10) Will the F179WT work on a beveled edge door or only a square edge door?
Square corners on the leaves, which is the standard square corner prep and it works with both square and beveled edge doors when specified that way on the order. If your existing hinges have rounded corners, this will not drop into that mortise without work, you would need a radius corner hinge or you will be squaring off the pocket.
11) Does the F179WT mortise into both the door and the frame, or is one leaf surface applied?
Both leaves mortise in. Full mortise means one leaf recesses into the door edge and the other into the frame rabbet, so nothing sits proud and only the barrel shows with the door closed. Budget prep time for routing both sides, this is not a surface applied hinge you can screw onto an unprepped frame.
12) I need a corrosion resistant hinge for an exterior or wash-down opening instead of the steel F179WT. What are my options?
Two directions. The Don-Jo BB94545 is a 4-1/2 inch by 4-1/2 inch full mortise ball bearing hinge in stainless steel with a square corner, standard duty. The Don-Jo BB84545 is a 4-1/2 inch by 4-1/2 inch full mortise ball bearing hinge in brass, finished satin chrome, also standard duty. The BEST F179WT is a steel hinge, so on openings where the base material matters, those two change the metal. Both are conventional hinges rather than wide throw, so confirm the opening does not depend on the extended throw before substituting.
13) Is the Hager 1541 an acceptable substitute for the BEST F179WT on a commercial door?
No. The Hager 1541 is a full mortise plain bearing residential hinge in stainless steel with a 5 knuckle design. It shares the plain bearing action and knuckle count with the F179WT, but the F179WT is specified commercial and medium duty for office, healthcare, educational, retail and institutional openings. On a commercial door under that kind of traffic, stay with a commercial-rated hinge; the 1541 is built for residential service and is not wide throw.
14) What is finish 639 on the BEST F179WT?
639 is satin bronze on a steel base. It reads as a warm, muted bronze rather than a polished one, and it is what you match to existing bronze lever trim and closers in an older commercial interior. Steel base means it is intended for interior openings, not coastal or wash-down exposure, where you would be looking at a stainless hinge such as the Don-Jo BB94545.
15) Where do I find the hinge size chart and mortise prep dimensions for the BEST F179WT?
BEST publishes the sizing and prep data for its 5 knuckle hinges in the Stanley Security 5 knuckle hinge catalog, along with a general hinge information document, a hinge size chart, and a step by step installation guide, all of which accompany the F179WT. Use the size chart to confirm the hinge width against your door thickness and trim projection before you cut the frame, and the installation guide for template hole locations.
