FAQ Knowledge Articles

A custodial limiter is placed on the unit in the factory (if ordered that way, or on very large units). It requires special tools in order to remove them.

It is not recommended that the custodial sash limiters be removed. They are there for safety purposes.

However, should a situation arise where it must be removed, you will need to contact your local Marvin dealer (or maybe call Marvin Customer Service) to get the appropriately-sized and shaped drill bit to assist in removing the limiter.
