ROFU 21990 – Frequently Asked Questions
1) What is the ROFU 21990 glue kit actually used for?
It's an adhesive kit for bonding mounting brackets to glass on glass door installations. When there is no frame or stile to drill and screw into, the bracket gets glued to the glass leaf instead. It is a non-electronic accessory that supports a mag lock or electronic access control installation rather than being part of the powered hardware itself.
2) Can I use the ROFU 21990 on a frameless all-glass door where I can't drill?
That is exactly the case it's made for. On a frameless or all-glass leaf you cannot through-bolt a bracket, so the 21990 adhesive bonds the bracket directly to the glass surface. If your door has an aluminum top rail or stile deep enough to drill and tap, you don't need a glue kit at all, and a mechanically fastened bracket is the stronger install.
3) Does the ROFU 21990 glue kit include the mounting bracket?
No. The 21990 is the adhesive kit only, sold to mount brackets on glass. The bracket, the lock or strike it carries, and any armature hardware are ordered separately as part of the access control package.
4) Is the ROFU 21990 suitable for a residential glass entry, or is it commercial only?
ROFU classifies the 21990 as commercial door hardware. It's intended for commercial glass door openings, typically storefront and interior glass entries where access control hardware is being mounted. Nothing stops it being used on a residential glass door, but it is specified and sold as a commercial item.
5) Is the ROFU 21990 an electrified part that needs to be wired?
No wiring involved. The 21990 is a purely mechanical adhesive kit, listed as non-electronic. It's an accessory used alongside electronic access control hardware, but it draws no power and has no leads or terminals to land.
6) Is there more than one version of the ROFU 21990 glue kit to choose from?
One configuration only, model 21990. There are no size, finish, or quantity options to specify when ordering, so there's nothing to get wrong on the order form.
