About the Pro-5 by Jackloc Key-Locking Cable Window Restrictor
The Pro-5 by Jackloc is a key locking cable window restrictor. It provides great versatility in domestic and commercial environments. The restrictor can fit most window sizes and types, including uPVC, Timber and Aluminium frames.
This key-operated lockable window restrictor provides the flexibility to allow the window to be fully opened when required and to be restricted to 100mm opening when needed.
The Pro-5 by Jackloc key-locking cable window restrictor is incredibly strong, with a high tensile stainless steel cable, security screws and heavy-weight body. Despite this high level of security the window restrictor is very easy to fit.
The window cable lock restrictor is tested to withstand a force of 3,600 newtons, exceeding all relevant standard requirements. The product comes with hardened and zinc coated grade four security screws to help keep homes safe and is also available in a range of bespoke RAL colours.

A huge thank you to Jackloc®️ MD Eric Collins and the team.
I have previously purchased Jackloc®️Pro 5 window locks. The locks are solid, secure, safe and will end window that’s fitted with a Jackloc®️ makes it impossible for the window to open more than that pre-set by the restrictor.
I had a spare window lock, and I recently came to fit it, but unfortunately I had misplaced the special security screws that are needed to secure the Jackloc®️and restrictor.
I emailed the company, and without any questions, a complete new set of screws were posted out to me.
Jackloc®️, as a company clearly have their Customers interests at the centre of its business.
Thank you Eric, and the team for first class Customer support. Your 5 ***** are well earned.

As an independent British Locksmith living and working in Cyprus it is very difficult to get hold of quality security products.
In the past I have fitted a few Pro-5’s and I have been extremely impressed with the quality, ease of fitment and strength of this product. Customers have also commented to me, how secure they feel, with this fitted to their windows.
I have now become a supplier of Jackloc in Cyprus, and look forward to supplying many more of these quality products to my customers.

Great service and sturdy locks
The locks are great quality and work very well. I was a bit sceptical about drilling into our PVC windows but these were easy to install and feel like they will last. The customer service is also excellent.
