If you have been considering a window restrictor but have been put off by the thought of complicated fitting take a look at our window restrictor fitting instructions.

Window restrictors allow the width to which a window opens to be restricted, which is useful for security as well as for the safety of children and other vulnerable people. This step by step guide shows how quick and easy it is to fit a window restrictor with just some basic DIY skills and a few minutes.

To fit a window restrictor you will need:

Drill
Pencil
Flat head screwdriver
Note that the Jackloc window restrictors are provided with hardened steel security clutch screws, which once fitted can not be removed, but alternative screws can be used if preferred.

Window Restrictor Fitting Instructions

We recommend you fix Part B (the lockable part) to the fixed frame, cill or wall and Part A (with the restrictor cable) to the opening window frame.

To fit part B: Place Part B on the fixed window frame or wall and mark the drill holes with a pencil. Next drill the pilot holes for Part B with a 3mm drill bit and then screw in the screws with a flat head screwdriver.

Check Part B is securely attached to the window frame.

To fit Part A : Measure the required distance you would like the window to be restricted to from Part B, Health & Safety recommend 100mm opening. Mark the drill holes for Part A with a pencil. Close the window and drill the pilot holes and then  screw in the screws with a flat head screwdriver. Place the supplied screw caps covers in Part B.

Maintaining the Jackloc
1. Clean the body and cable components occasionally with a damp cloth only.
2. Frequently check that the key lock or push button where relevant, operates and spray lubricant into the barrel lock as
necessary, and at least every 6 months. Locks that are located in a marine or heavily polluted environment should be sprayed with lubricant every 3 months.

IMPORTANT
The Jackloc window restrictor can be fitted to most window and door materials and styles including UPVC windows, timber, aluminium and steel.

The Jackloc window restrictor must not be fitted to decaying timber, corroding steel or units that are in disrepair
