BEST T 689 – Frequently Asked Questions

1) What is the BEST T arm and what part of a door closer does it replace?
The T is a track arm for a door closer, not a complete closer. It's the linkage that rides in the track and connects the closer body to the frame, sold as a replacement component for BEST closer assemblies. If your closer body still pumps and controls fine and only the arm is bent, worn, or missing, this is the piece you replace. If the cylinder itself is leaking, you need a closer body instead.
2) Is the BEST T track arm for pull side or push side mounting?
Pull side, door mounted. The geometry is specific to that setup, so it will not align correctly on a push side (parallel arm) or top jamb installation. On a pull side door-mounted closer the body sits on the door face on the side the door swings toward you, and the track mounts to the frame face above the door.
3) Will the BEST T track arm fit any door closer I already have?
It's built as a direct replacement for compatible BEST closer assemblies, so match it to a BEST body set up for pull side door-mounted track operation. Arm-to-body spindle splines and track profiles differ between manufacturers and between arm styles, so pull the model off the closer body before ordering rather than matching by appearance.
4) Should I use a track arm or a standard regular arm closer on a pull side door?
A track arm keeps the linkage low and tight to the door, which is what facilities want in corridors, schools, and healthcare where a projecting elbow arm gets grabbed, hung on, or damaged. A standard regular arm projects out from the door and is easier to adjust for opening force, but it's exposed. The BEST T is the track style, and it only works with a closer body and track built for track operation; it is not a drop-in swap for a regular arm closer.
5) What finish does the BEST T closer arm come in?
One finish: 689 aluminum painted. That's the standard sprayed aluminum finish used across most commercial closers, so it blends with existing 689 closer bodies and covers on the other openings in a building. If your other closers were specified in a plated or dark bronze finish, the arm will not match them visually.
6) Is the BEST T arm rated for high-traffic commercial doors or is it a residential part?
It's a commercial part. BEST built the T arm for commercial-grade closer service in office buildings, schools, hospitals, retail, warehouses, multi-tenant residential, and government facilities, which is where closers cycle hardest. For a light-duty residential closer this is more arm than the opening needs and the mounting will not match.
