BEST A3-C1 – Frequently Asked Questions

1) What is the difference between an offset hung pivot set and a center hung set, and which one is the BEST A3?
The BEST A3 is an offset hung pivot set, meaning the pivot point sits off the door's centerline near the hinge edge so the door swings in one direction from an offset axis and the door edge stays close to the frame. Center hung sets place the pivot on the door's vertical centerline, which lets the door swing both ways and is the usual choice for balanced or double-acting doors. If the opening is prepped for a center hung pivot, the A3 is the wrong part, and a center hung set such as the ABH 0117.75 or the ABH 0127 is what you want instead.
2) What do I have to specify when ordering a BEST A3 offset pivot set?
There is one option axis to pick, and eleven choices on it: C1, C2, D1, D3, D5, D6, D7, D8, D9, D10 and D11. Pick the code that matches the rest of the BEST system you are standardizing on, because the A3 is built around BEST's Premium core and masterkey program, and the option code is how that gets tied into an existing key system.
3) What other offset pivot sets could I use instead of the BEST A3?
For a straight offset swap, the ABH 0117 is a standard duty 3/4 inch offset pivot set rated for doors up to 300 lbs and fire rated, and the ABH 0117.25 is a heavy duty 3/4 inch offset set for doors up to 250 lbs, also fire rated. The Calibre Door Closers PV1000 is another 3/4 inch offset flush pivot set. Choose on the offset dimension your frame is prepped for and on door weight. What none of those give you is the BEST Premium core and masterkey tie-in, which is the reason to stay with the A3 if you are standardizing a facility on BEST keying.
4) What is a comparable offset pivot set to the BEST A3 for a fire-rated commercial door?
The ABH 0117 is an offset pivot set with a 3/4 inch offset rated for doors up to 300 lbs, and it carries a fire rating the same way the BEST A3 offset hung pivot set does. Both are offset hung applications, so the door and frame prep stays in the same family. The ABH 0117 is listed as standard duty, while the ABH 0117.25 covers the same 3/4 inch offset in a heavy duty build for doors up to 250 lbs.
5) Can the BEST A3 be used on a door tied into an electronic access control system?
Yes. The A3 system is flagged for electronic integration, so it is intended to be used on openings where the access control is electronic rather than purely mechanical. The Premium core side of the system is what carries over into BEST's masterkey program, so you can run the same key hierarchy across mechanical and electronic points in a facility.
6) Does installing the A3 pivot set require cutting the door and frame, or is it a surface mount?
It is a prepped install, not a surface application. The A3 requires templating the pivot locations on both door and frame, then drilling and routing the door and frame as the manufacturer specifies for offset hung pivots before the hardware is fastened and torqued. On a fire rated assembly that prep has to follow the manufacturer's instructions to keep the rating intact, so a retrofit onto an existing butt-hinged door means new prep, not a swap.
7) I just need a plain offset pivot with no key system. Is there a simpler option than the BEST A3?
Yes. The BEST A3 offset hung pivot set carries Premium core technology and is set up for masterkeying and electronic access integration. If the opening does not need any of that, the Calibre Door Closers PV1000 is a 3/4 inch offset flush pivot set in the CA/Hardware Series and is a straight mechanical offset pivot. The ABH 0117, a 3/4 inch offset set for doors up to 300 lbs, is another mechanical-only route that keeps the fire rating.
8) Is the BEST A3 pivot set meant for commercial openings or will it work in a house?
It is a commercial-grade product. The A3 is classified for commercial use, and the applications it is built for are office buildings, schools, healthcare, government and municipal buildings, industrial and warehouse facilities, multi-tenant residential, and fire rated door assemblies. On a single-family residential door it is more hardware than the opening needs.
9) Why does BEST call these Premium cores, and does it matter for a facility already keyed to BEST?
Premium refers to the key and core platform the A3 uses: the keys are larger and heavier than standard keys so they hold up better under heavy daily use, and the cores are supported by BEST's masterkey program. For a facility already running BEST keying, that is the point of buying the A3 rather than a generic offset pivot set, because the same key hierarchy and level of control extends to this opening.
