BEST DAP-3 626 – Frequently Asked Questions

1) Will the DAP-3 pivot work on a 1-3/4 inch commercial door?
Yes. The DAP-3 is built for both 1-3/8 inch (35 mm) and 1-3/4 inch (44 mm) door thicknesses, so it covers the standard commercial 1-3/4 leaf as well as the lighter 1-3/8 interior door.
2) Does the DAP-3 pivot need floor support, or does it mount to the frame?
Both. The bottom bracket is frame-mounted but floor-supported, so the floor under the jamb has to be sound enough to carry the door load. The top uses a walking beam header plate, which speeds up hanging the door. Plan the opening so the bottom bracket has solid bearing before you set it.
3) Can a standard commercial butt hinge be used instead of the BEST DAP-3 double acting pivot?
No. The DAP-3 is a double acting pivot set that lets a commercial interior door swing both directions, with a walking beam header plate, a frame-mounted floor-supported bottom bracket and 1/4 inch solid brass frame plates. Mortise butt hinges such as the Hager BB1168 full mortise ball bearing heavy duty hinge or the Ives 3CB1HW steel heavy weight concealed bearing full mortise hinge swing the door one way only and mount on the jamb face rather than at head and floor. If the opening must swing both ways, a butt hinge is not a substitute regardless of its weight rating.
4) What should I use if the door needs to self-close rather than free swing on a pivot?
The BEST DAP-3 is a double acting pivot assembly with an oil impregnated bronze bearing at the top and a ball bearing assembly at the bottom; it carries the door but provides no closing force. For a single-swing door that must return closed on its own, the Stanley Security 2060R full mortise spring hinge in 4.5 inch by 4.5 inch square corner, ferrous steel base, is a heavy duty hinge with built-in spring closing. Note it is a conventional single-acting mortise hinge, so the opening has to be prepped for a jamb-mounted hinge rather than head and floor pivots.
5) My door is over 135 lbs or wider than 3 feet. What heavy duty hinge options work instead of the DAP-3?
The DAP-3 is rated for doors up to 135 lbs and not exceeding 3 feet in width, so a heavier or wider leaf needs conventional heavy duty mortise hinges. Heavy duty options include the Hager BB1168 non-removable pin full mortise ball bearing hinge, the Ives 3CB1HW steel heavy weight three knuckle concealed bearing full mortise hinge, and the Stanley BB855 double weight prison hinge at 5 inch by 6 inch, furnished with no holes and not swaged. All are single-acting, so confirm the opening does not require two-way swing before switching.
6) Can I use a double acting pivot on a door with a big undercut for airflow?
The DAP-3 handles undercuts from 3/4 inch (19 mm) to 1 inch (25 mm), adjustable in 1/16 inch (1.6 mm) increments. That covers most return-air undercuts on commercial interior doors. Anything deeper than 1 inch is outside its range.
7) Why choose a double acting pivot instead of butt hinges on a swing-both-ways door?
Butt hinges only swing one direction. A double acting pivot like the DAP-3 lets the leaf swing both ways and self-center, which is what you need on a bathroom entry or service door with traffic going both directions. If the door only swings one way, a conventional mortise hinge such as the Ives 3CB1HW heavy weight concealed bearing hinge is the simpler answer.
8) What keeps a double acting pivot swinging smoothly over years of traffic?
In the DAP-3, the top door plate carries an oil impregnated bronze bearing and the bottom door plate uses a ball bearing assembly. The frame plates are extra heavy 1/4 inch (6.35 mm) solid brass, so the mounting points do not deflect under a 135 lb leaf.
9) How far off the frame should the door sit when installing the DAP-3?
Set the leaf at a 1/8 inch (3.2 mm) inset from the bathroom face of the frame, then cycle it through the full swing both directions before final tightening. Getting that inset right is what keeps the door centering cleanly.
10) I need to run power through the door for an electrified lock. Does the BEST DAP-3 do that?
No. The DAP-3 is a mechanical double acting pivot with brass frame plates and bearing assemblies and carries no wiring path. For power transfer through the hinge, the Command Access ETH-BB68 is a heavy duty five knuckle energy transfer hinge on a steel base, and the ETH-CB70 is the standard weight three knuckle medium duty version. If you also need door position monitoring, the Command Access ETM-BB68 adds an integrated door position switch. The Stanley CECB1900R54L is a three knuckle concealed bearing concealed conductor architectural hinge, steel full mortise, 4-1/2 by 4-1/2, square corner, left-handed, 4-wire.
11) Can I use the BEST DAP-3 on a residential interior door instead of standard hinges?
The DAP-3 is specified for commercial double acting interior doors of 1-3/8 inch or 1-3/4 inch thickness and requires floor support for the frame-mounted bottom bracket plus a door undercut between 3/4 inch and 1 inch. A standard residential interior door swinging one way is served by conventional hinges such as the Deltana DSB35 3-1/2 inch square hinge pair, the Emtek 91013 residential plain bearing 3-1/2 by 3-1/2 square corner plated steel pair, or the Schlage Residential S3P1010 3.5 inch square corner plain bearing mortise hinges in a three-pack. Choose the DAP-3 only when two-way swing and the floor prep are both part of the job.
12) For a secure or detention opening, is the DAP-3 the right choice?
The DAP-3 is a double acting pivot for commercial interior doors up to 135 lbs and offers no security pin or tamper feature. For openings where the door must resist removal or attack, the Hager 990 STEEL full surface prison hinge at 3 inch by 4 inch with welded tip is heavy duty, the Stanley BB855 double weight prison hinge is 5 inch by 6 inch, and for a non-removable pin option the Hager BB1168 NRP full mortise ball bearing hinge or the Deltana CSB45N 4-1/2 inch square hinge pair with non-removable pin applies. Deltana also lists the DE44R5TA 4 inch security hinge with 5/8 inch radius in steel.
13) The frame is not prepped for a full mortise hinge. What are my options besides the DAP-3 pivot?
The DAP-3 mounts at the header and a frame-mounted bottom bracket with floor support, which avoids jamb mortising but requires a solid floor and a door undercut of 3/4 inch to 1 inch. If the floor cannot carry the bracket, half mortise and full surface hinges are the other routes: the Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch standard weight steel, and the Hager 990 STEEL is a full surface hinge at 3 inch by 4 inch with a welded tip. The Hager 920 is a full mortise concealed plain bearing two knuckle steel hinge if the jamb can be prepped after all.
14) What finishes does the BEST DAP-3 pivot come in?
Two: 605 bright brass and 626 satin chrome. If the rest of the openings in the building are on satin chrome lever trim, 626 is the match; 605 pairs with polished brass hardware.
15) Will the 626 satin chrome DAP-3 match hinges I already have on nearby doors?
The DAP-3 is offered in 605 bright brass and 626 satin chrome. Matching across an opening group is usually a finish-family decision rather than a part-for-part match, since peers such as the McKinney MPB79 MacPro five knuckle standard weight hinge, the Emtek 94013 heavy duty ball bearing 3-1/2 inch square corner plated steel pair, and the Orca 4-1/2 by 4-1/2 square corner ball bearing commercial hinge are separate hinge lines. Confirm the finish code on the existing hardware before ordering the pivot in 605 or 626.
16) Is a non-ferrous or decorative hinge a reasonable swap for the DAP-3 in a healthcare or hospitality corridor?
Only if the door swings one way. The DAP-3 uses solid brass frame plates and is built for double acting commercial interior doors up to 135 lbs. For a single-swing corridor door where appearance or corrosion resistance drives the choice, the McKinney T2314 is a non-ferrous standard weight five knuckle hinge rated medium duty, and the McKinney SQ3331 is a square barrel two knuckle decorative hinge at 4-1/2 by 4-1/2, standard duty. Neither carries the DAP-3 weight rating or the two-way swing.
