The Whitco CYL4 Patio Bolt in Black is a premium bolt with concealed fixing, ideal for residential sliding and hinged doors. It allows the door to be bolted in the closed or venting position.
A 9.5mm steel bolt gives 49mm of bolt extension from a solid zinc diecast body. A stainless steel ferrule is supplied for timber applications, with a flat steel keeper for where the bolt does not engage the door frame.
The CYL4 cylinder can be keyed alike to most Whitco door locks using a 5-pin or 6-pin C4 profile key, and to CYL4 window locks. Two Whitco keys are included.
