The Fastest, Cleanest Way to Install Angel Locks in Sash Windows

The SCRIBE-MASTER Angel Lock Jig+ (ALJIG) is the professional’s solution for quickly installing Angel Ventlock® sash window locks using a router. This innovative jig allows for fast, accurate routing directly on fitted sash windows—no removal required.

Engineered for ease and precision, the ALJIG includes dedicated inserts for both standard and lockable Angel Ventlock® devices, allowing for either countersunk or surface-mounted installations. Whether you're a tradesperson, installer, or window manufacturer, this jig will transform how you fit child safety locks in traditional sash windows.

Use the jig in-situ with a vacuum extraction system for minimal cleanup, or clamp it to a bench using the built-in clamp slots. The ALJIG is supplied with a European or USA guide bush depending on your region.
