Lockwood Wedgeless DLX Lock - Face Fix 4mm and 6mm Backsets - 345-346
The Lockwood Wedgeless DLX Lock is a locking face fix window fastener designed for aluminium and PVC window applications. This innovative Interlock design incorporates the wedge into a folding flap attached to the base of the handle, removing the need for a separate wedge component.
The Wedgeless Deluxe uses a longer 107mm handle and a push button cylinder locking function, making it a practical option where secure operation and straightforward daily use are both important. It is suited to residential awning and casement windows.
This range is available in both 4mm and 6mm backset configurations. Finish variants are available across the range, while the main mechanical difference is the backset selection.
Typically ships in 1 Day for Black variants. Selected finish variants may have longer dispatch times.

Frequently Asked Questions
What makes this fastener “wedgeless”?
The wedge function is built into a folding flap attached to the base of the handle, so a separate wedge is not required.
How do I choose between 4mm and 6mm?
The correct backset depends on the window profile and the required fastener geometry. It should match the window setup already in use or the installer’s specification.
Is this suitable for aluminium and PVC windows?
Yes. The supplied product data states it is designed for use with either aluminium or PVC windows.
Additional Information
- Wedgeless window fasteners are commonly chosen where installers want a cleaner look and fewer separate frame mounted parts.
