Ergonomically designed for easy operation, the button is simply pushed and the cable inserted into lock body and the key turned to lock. To unlock simply insert the key and remove, press the button and release the cable. The locking restrictor can also be used instead of a traditional door chain to secure timber door too. Available in either White, Brown, Polished Gold or Polished Chrome finishes to match any style of window or door.

Operation: Key required to lock and unlock. To Lock – Push button in and insert cable into lock body. Let go of button and pull cable until you hear a click. Check cable is secure.

Faulty Goods & Guarantees

In the unlikely event that a product purchased from ERA/ Response Electronics does not operate upon arrival or develops a fault during the warranty period, the following applies:


  1. To report a fault and to arrange the return of faulty goods please contact our Customer Helpline on 0345 257 2500.
  2. One of our helpline technicians will discuss the nature of the fault with you, as we often find that 'faults' are configuration or compatibility issues that can be resolved over the telephone and in such cases, we can help you get your product working, saving you the trouble of returning a non-faulty item. This in no way affects your statutory rights and is simply something we ask our customers to perform in order to ensure that products returned are genuinely faulty and to speed up the product exchange/refund/replacement process. Upon testing the returned product, should it be found not to have a fault then we will contact you to discuss further.
  3. If we agree to Refund your Return Postage Costs, we will only do so, providing you supply us with proof of return, such as a scanned copy or photocopy of the Receipt for Postage. The Returns Reference Number as obtained from our Customer Helpline must be quoted in all correspondence.
  4. We will only refund items returned to us by the agreed method of postage.  We are not responsible for the difference in postal costs where you have chosen to return the product to us by a more expensive means


Please ensure you return the product in its original packaging and with all product component parts as supplied, including but not limited to: manuals, accessories, cables.


Please Note: If a receipt is not provided we are not obliged to refund your postage. The Postage Frank mark on the package is not Proof of Postage and will not be accepted.
