We recommend protecting vulnerable windows that could be attacked to access the property with laminated glass. Burglar entry is commonly through the door but when this is blocked they will go to plan B.

features

Another entry method is through older central lock windows that can be levered open from the corner. Sash jammers cost little and can be installed quickly to give the same protection as new multi-lock windows.

features

These patented high-security door handles are security accredited to prevent access to the sides of the lock so they cannot be gripped or broken being ten times stronger than a conventional door handle.

Fantastic, trustworthy local company. We've had two new doors fitted by Sash Jammers company SheffLOCK and we are very happy with them. Both doors were installed to a very high standard of quality by Glenn, who left the work area completely neat and clean on both occasions. Debi and Diane in the office are also very friendly and helpful during the ordering process. Thank you! :)

I have been very pleased with my experience of Sash Jammers company SheffLOCK. I received a free visit from Chris to give me advice on security, there was no pressure involved, and after I had decided what I wanted it was fitted within a matter of a few days. The engineers who did the work were friendly and helpful, and completed the job very quickly. I had one slight difficulty with a lock which had been fitted. When I raised this with Chris he immediately arranged for the lock to be changed at no extra charge. I certainly recommend Sash Jammers company SheffLOCK. Their products are good, they respond to email communications immediately, and they are obviously committed to achieving excellent customer satisfaction.
