BEST FBB173 4-1/2 26D – Frequently Asked Questions

1) What is a half surface hinge and when do I need one instead of a full mortise hinge?
A half surface hinge like the BEST FBB173 mortises into the frame but surface-applies to the door face. That's what you want when the door's edge rail won't hold screws, which is the common failure on wood, kalamein, and mineral core doors. The FBB173 pairs a mortised frame leaf on a hollow metal frame with a surface leaf on the door. If the door edge is solid and takes screws fine, a full mortise hinge is the normal choice, and Hager's 1191 full mortise 5-knuckle is one we carry.
2) Will the BEST FBB173 work on a 1-3/4 inch door?
Yes, and that is the thickness it's built around. The FBB173 ships with machine screws and grommet nuts sized specifically for 1-3/4 inch doors, and the hinge supports doors up to 1-3/4 inch. Thinner doors would need different through-bolt hardware than what comes in the box.
3) Do I have to order the BEST FBB173 left hand or right hand?
No handing to specify. The flush tips and pins on the FBB173 are reversible, so the same hinge works on either hand of door. You order by size and finish only.
4) Can the BEST FBB173 hold a heavy door on a high traffic entrance?
Not the right hinge for that. The FBB173 is medium duty, built for medium weight doors with average frequency of use. A heavy door, or an opening that runs constant traffic, calls for a heavy weight hinge instead. Where the FBB173 does fit is offices, schools, healthcare corridors, and apartment openings with normal use.
5) Is the Hager 1173 the same hinge as a BEST FBB173?
They share the half surface mounting and the medium duty rating, and both are steel 5 knuckle commercial hinges, but they are not the same bearing. The Hager 1173 is a plain bearing hinge; the BEST FBB173 runs two permanently lubricated non-detachable ball bearings. On an opening where the specification calls out ball bearings for frequency of use, the 1173 does not answer it. Where a plain bearing is acceptable, the 1173 is the half surface equivalent.
6) What is the closest half surface hinge to a BEST FBB173 if I need ball bearings on a half mortise door instead?
The BEST FBB173 is a half surface, ball bearing, 5 knuckle medium duty hinge with a removable pin. When the door and frame are prepped for half mortise rather than half surface, the Hager BB1109 covers the same bearing and duty picture: it is a half mortise ball bearing hinge, 5 knuckle, standard weight, medium duty. Bearing type and knuckle count carry over; the leaf mounting is what changes, so confirm which leaf mortises into the door before ordering.
7) The door edge holds screws fine and it is a standard mortise prep - do I still need the FBB173?
No. The BEST FBB173 exists for medium weight wood, kalamein, or mineral core doors whose edge rails will not hold screws, which is why it mounts to the door face with machine screws and grommet nuts. On a sound door that takes a normal mortise prep, a full mortise hinge is the fit: the Hager 1191 is a full mortise plain bearing hinge, standard weight, 5 knuckle, and the Hager 800 is a full mortise plain bearing hinge in a 3 knuckle standard weight medium duty form. Both are plain bearing, so match that against what the opening's frequency of use requires.
8) What sizes and finishes does the BEST FBB173 half surface hinge come in?
Three sizes, 4 x 4, 4-1/2 x 4-1/2, and 5 x 5 inches, each in six finishes: 600 primed for painting, 632 bright brass, 633 satin brass, 639 satin bronze, 640 dark satin bronze, and 626 satin chrome. Every size is offered in every one of those finishes. Corners are square, so the surface leaf sits on a flat door face without radius prep.
9) Can I take a door down without unscrewing the hinges?
Yes. The FBB173 uses a removable pin, so you pull the pin and lift the door off the frame leaf, then set it back on the same pin. That is the practical difference from a non-removable pin hinge when you're pulling doors for painting, moving furniture, or swapping a leaf. Note the pin is removable from either side, so it does not by itself provide security on an out-swinging exterior opening.
10) How is the FBB173 half surface hinge fastened to the door?
Through the door, not into the edge. The FBB173 comes packed with machine screws and grommet nuts sized for 1-3/4 inch doors, so the surface leaf bolts through the door face rather than relying on wood screws in a rail that won't hold. Manufacturer documentation also recommends considering back plates with these hinges. The frame leaf mounts to the hollow metal frame.
11) What size hinge should I use, 4 inch, 4-1/2 inch, or 5 inch?
Hinge size follows door thickness and door width. The FBB173 comes in 4 x 4, 4-1/2 x 4-1/2, and 5 x 5. On 1-3/4 inch commercial doors, 4-1/2 inch is the usual size, moving to 5 inch as the door gets wider so the leaf clears the trim; 4 inch suits lighter and narrower doors. BEST publishes a hinge size chart that maps door thickness and width to hinge size if you want to confirm before ordering a run of openings.
12) I am standardizing hinges across a building - can I run the Hager 800 everywhere and skip the FBB173?
Only on the openings the 800 suits. The Hager 800 is a full mortise, 3 knuckle, standard weight medium duty plain bearing hinge, so it needs a door edge that accepts a mortise and screws. The BEST FBB173 is the half surface answer for wood, kalamein, or mineral core doors with edge rails that will not hold screws, hung on hollow metal frames, and it is a 5 knuckle ball bearing hinge. A single-hinge standard across a mixed building usually breaks on those problem doors, so plan the 800 for the sound mortise openings and the FBB173 for the rest.
13) Which hinge gives ball bearing operation without the face-mounted half surface leaf?
The Hager BB1109 is the ball bearing option that mortises: half mortise, 5 knuckle, standard weight, medium duty. The BEST FBB173 keeps its door leaf on the face of the door, secured with machine screws and grommet nuts sized for 1-3/4 inch doors, because it is built for edge rails that will not hold screws. Choose on the door condition - a door that can be mortised takes the BB1109, a door that cannot takes the FBB173.
14) I need to match the FBB173 finish to existing hardware on the rest of the building. Which finishes are steel?
The brass and bronze finishes on the FBB173, 632 bright brass, 633 satin brass, 639 satin bronze, and 640 dark satin bronze, are plated over steel, as is 626 satin chrome. If you're painting to match a door color, order 600 primed for painting and finish it on site. Non-ferrous hinges use stainless steel pins for corrosion resistance.
15) Is the BEST FBB173 a commercial hinge or a residential one?
Commercial. The FBB173 is a 5-knuckle steel hinge specified for commercial and industrial openings on hollow metal frames, and it's the kind of hinge used in office buildings, schools, healthcare facilities, and multi-tenant residential corridors. It is not a residential-grade butt hinge.
16) I need a painted-out hinge to match a field-painted frame - what are my options against a plain bearing Hager?
The BEST FBB173 comes in a 600 primed for painting finish in 4 x 4, 4-1/2 x 4-1/2, and 5 x 5, alongside 632 bright brass, 633 satin brass, 639 satin bronze, 640 satin bronze dark, and 626 satin chrome. It is the ball bearing half surface hinge in that finish range. The Hager 1173 is the half surface comparable but is a plain bearing hinge, so the decision between them is bearing type rather than mounting.
