4th Generation Lock-Tilt Combo

4th Generation Lock-Tilt Combo is a single window hardware component that performs 4 functions: 4 point locking, sash tilt, and now a WOCD compliant vent stop thus eliminating the need for adding a separate vent stop or other WOCD components on the window.

In addition, as WOCD compliancy becomes more widely accepted, manufacturers can offer this safety feature without adding additional hardware or extending the process time for fabrication. Because the WOCD functionality is hidden, manufacturers are able to maintain the aesthetics of their current window.

The finished window yields a 4 point multi-locking system, dual tilting sashes, a secure venting feature and dual WOCDs as a standard, but only the locks are visible. All the other features are internalized and work from the lock itself. Once the fabrication and material cost of tilt latches, vent stops, and WOCDs are backed out the system is a wash. Think of the marketing sizzle and the retail opportunity.

OK, this is cool.

The only lock-tilt system ever to be tested by a certified lab.

Our engineers took the 4th Generation Lock-Tilt-Combo to Architectural Testing Labs in Pennsylvania and ran a series of cycling and stress tests.
