Dormakaba MOD SISJH 689 – Frequently Asked Questions

1) What reveal does the Dormakaba MOD-SISJH closer arm cover for top jamb mounting?
The MOD-SISJH arm is built for top jamb mounting on frame reveals from 3-1/2 inches to 6-1/2 inches. Measure from the face of the door to the mounting surface on the frame soffit: if that dimension falls in that band, this arm covers it. Outside that range, a top jamb arm with a different reveal bracket is required.
2) What does the spring cushion hold open on the MOD-SISJH actually do?
Two things in one arm. The extra heavy-duty spring cushion absorbs the door when it is thrown open hard, which protects the closer and the frame in high-traffic openings and where wind catches the door. The hold open lets the door stay parked at a set position for moving carts, deliveries, or accessibility. If you do not want a door that stays open, order a non-hold-open arm instead.
3) Can I replace just the closer arm instead of the whole Dormakaba closer?
That is the point of the modular design. The MOD-SISJH is sold as a replacement arm within the Dormakaba MOD modular closer platform, so a bent or worn arm can be swapped without pulling and re-prepping the closer body. It mates to compatible Dormakaba Modular Closer units, so confirm the body on the door is a MOD series closer before ordering.
4) When should I use a top jamb closer arm instead of a regular or parallel arm?
Top jamb mounting puts the closer body on the frame face above the opening with the arm reaching back to the door, so it is the choice when the door face cannot take the closer body or when a regular (pull side) or parallel arm mount is not workable on the opening. The Dormakaba MOD-SISJH is a top jamb arm specifically, so it will not convert a closer to parallel arm or regular arm mounting.
5) What finishes does the Dormakaba MOD-SISJH arm come in for matching existing hardware?
Three finishes: 689 aluminum, 693 black, and 695 dark bronze. Those are the standard BHMA painted closer finishes, so 689 matches most clear-anodized aluminum storefront and hollow metal work, 695 matches dark bronze frames, and 693 matches black doors and frames. Pick the one that matches the closer body already on the opening so the arm does not stand out.
6) I need to order a replacement arm for a Dorma closer. What model do I ask for?
Ask for the Dormakaba MOD-SISJH, listed as model MOD SISJH. It is the top jamb, extra heavy-duty spring cushion hold open arm in the modular closer line. Specify the finish (689, 693, or 695) with the order, since that is the only option you choose on this arm.
7) Is the MOD-SISJH arm suitable for a school or hospital corridor door, or is it only light duty?
It is a commercial-rated component, built for high-traffic institutional openings such as schools, hospitals, offices, retail, warehouse, government buildings, and multi-tenant residential. The extra heavy-duty spring cushion is there for exactly that kind of abuse. It is not a residential-duty part.
