Whitco CYL4 Push Lock - Window Lock

The Whitco CYL4 Push Lock is a high security window lock designed specifically for sliding aluminium windows. Simple to operate — just push the button to lock — it's an effective and unobtrusive solution for ground-floor windows, bedrooms, or any sliding window where security matters.

The lock body sits flush against the frame with concealed fixing, so there's nothing visible to tamper with from the outside. It's built from solid zinc diecast metal, meaning it resists the kind of force and attack that cheaper plastic alternatives can't handle.

CYL4 One Key Convenience The Push Lock is part of Whitco's CYL4 keyed security system, which means it can be matched to your other CYL4 window and door locks — one key operating everything. If you're fitting multiple window locks across the house, this is a significant convenience.

Ventilation without compromise The Push Lock allows you to lock the window in a partially open position, so you get airflow without sacrificing security.
