Winlock's Stronghold series is a six-point multilock system designed for sliding patio doors.  They are universally handed and are designed to be operated by patio lever type handles along with a euro cylinder.  These are not supplied with the lock so if you do need new handles and a cylinder, we have an offering of these available for you too.

These six hooks offer incredible security, and are situated bi-directionally (facing upward and downward) to remove any possibility of the door being lifted or shunted to mitigate the security of the hookbolts.  In addition to this security, the centre gearbox also offers an anti-lift bolt.  This will further deny any attempt to jemmy the door and gain unauthorised access. 

The level of security offered by these locks allows them to be PAS24 rated.

All external-facing components on this lock are made with Grade 430 Stainless Steel to minimise any corrosion issues, and achieving BS EN 1670 Grade 4 (240 NSS) with regards to its corrosion resistance.

It is worth noting that the keeps are sold separately; so you do not necessarily have to buy these if you are retrofitting an existing Winlock Stronghold installation unless you want to; but for new installations you will need a keep.  These are single-strip (one-piece) keeps that will accommodate all of the hooks and the anti-lift minibolt these locks offer.

Our product specifications are given in good faith but can be subject to manufacturer change without notice. Should an attribute be of essense to your purchase, please feel free to contact us first for confirmation.
