Norton Rixson RIX-900 689 – Frequently Asked Questions

1) What does the Norton Rixson 900 armature extension base actually do?
It adds 1-1/2 inches of projection between the closer arm's armature and its mounting point, so the arm sits at the right geometry when the frame depth, a glass door system, or a retrofit conversion won't let a standard mount land where it should. It's an installation accessory, not a closer itself, and it's meant for commercial door systems.
2) My closer arm won't reach the door on an aluminum storefront. Will a 1-1/2 inch extension base fix it?
That's the exact condition the 900 extension base is for. It gives 1-1/2 inches of added projection so the armature lands where the arm geometry needs it on deep frames, aluminum storefront, and glass door systems. If your shortfall is more or less than 1-1/2 inches, this base won't correct it, since the projection is fixed at that single dimension.
3) Does the Norton Rixson 900 extension base work with any brand of door closer?
It's built for use with compatible Norton Rixson door closers. Match it to the specific closer model you're mounting and check the closer's own installation instructions before ordering, since the base has to align with that device's armature mounting.
4) I'm converting an old closer over to a new Norton Rixson unit and the arm sits short. Is this the part I need?
Retrofit conversions are one of the named uses for the 900 base. When the new closer's arm doesn't reach because the existing mounting condition was set up for different hardware, the 1-1/2 inch extension restores the arm geometry rather than forcing you to re-drill the door or frame. Confirm the shortfall is close to 1-1/2 inches, because that projection is fixed.
5) How many extension bases do I order for a pair of doors?
One base per closer. Each unit provides the 1-1/2 inch projection for a single armature, so a pair of doors with a closer on each leaf takes two, and you'd order both in the same finish to keep the openings matching.
