Calibre Door Closers CA3020-VO-AL – Frequently Asked Questions
1) How much top rail depth does the Calibre CA3020-VO offset top arm need?
The CA3020-VO offset top arm assembly needs a top rail at least 7/8 inch deep. That is the governing dimension on this part: measure the top rail on the door leaf before you order, because a shallower rail will not take the arm and no shim or adapter changes that. Doors with a narrow top rail, common on some aluminum entrances, need a different arm arrangement.
2) Is the Calibre CA3020-VO top arm a replacement part or a complete door closer?
It is an arm assembly only, sold as a replacement part. There is no closer body, no cover and no spindle in it, so if the closer itself is failing you are ordering the wrong item. Buy this when the arm is bent, worn at the pivot, or missing from an existing Calibre installation and the closer body is still good.
3) What is the difference between an offset top arm and a standard top arm on a Calibre closer?
An offset arm carries the pivot point away from the closer body so the arm can reach a door leaf whose top rail sits off the closer centerline. The CA3020-VO is the offset, surface style version, so the arm mounts on the face rather than being buried in the rail. If the opening takes a straight in-line arm, the offset is the wrong shape for it.
4) Which model do I order for the Calibre VO type offset top arm?
Order the CA3020-VO-AL. The VO designation identifies the offset top arm type, and it is the single configuration this arm is built in, so there is no handing or length to specify on the order form.
5) Is the CA3020-VO arm suitable for a high traffic commercial entrance?
Yes, the CA3020-VO offset top arm is a commercial grade part, intended for commercial openings rather than residential doors. For a property manager standardizing a building, the practical check is the top rail: every leaf you plan to fit needs the 7/8 inch depth, otherwise the openings will not take a common arm.
