Whitco CYL4 Multi Bolt Window Lock

The Whitco CYL4 Multi Bolt is the most adaptable lock in the CYL4 range — particularly well suited to double hung windows, which can be tricky to secure properly. Where the Window Bolt uses a single fixed bolt, the Multi Bolt ships with three different bolt types, giving you the right fit for the application without improvising or ordering additional parts.

It can be face-fixed or side-fixed, making it easier to install in tight or awkward frames. Like the rest of the CYL4 range, the lock body is solid zinc diecast — built to resist attack, not just keep the window closed on a calm day.

Key features:

• 3 bolt types included — suited to a wide range of window applications
• Versatile face fix or side fix design
• Key to lock, key to unlock
• Locks in closed or fixed ventilation position (sliding and double hung windows)
• 8mm steel bolts
• Stainless steel ferrule for timber installations
• Concealed fixing — nothing exposed outside
