Review: excellent - I feel so happy that the windows are secure and safe. So strong and the kids are able to open their own windows in safety. have used on wood and PVC windows. Review: Good product but some limitations - I bought this product to use on a sliding patio door. It is a well made product. However when I installed it as illustrated, when unlocked, the cable part stood out perpendicular to the sliding door creating a hazard and also looking quite ugly. So I had to fashion a bracket from a piece of scrap angle iron so that the cable part was installed parallel to the sliding door. This bracket also had a hole in the middle so that the cable part could be withdrawn away from the door opening when not in use. Once this was done, the lock did its job perfectly. I know this sounds very confusing but unfortunately there is no way I can attach a photograph or a drawing here to illustrate the bracket I made. But I wish the company had provided this kind of bracket with the lock as it makes using the lock more practical. Also note The company provides only one key per lock so if you want a spare you will have to order two locks or get one cut. All locks have the same key. ## Features - Can be fitted to all materials - Cable Length: 200mm - Lockable by Key - Security screws provided - Finish: Black ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0087ZNGTW | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 608,079 in DIY & Tools ( See Top 100 in DIY & Tools ) 1,471 in Window Locks & Latches 1,550 in Safety Gates & Gate Extensions | | Colour | Black, Silver | | Customer Reviews | 3.8 3.8 out of 5 stars (9) | | Date First Available | 1 Jun. 2012 | | Finish | Painted | | Included Components | Screws | | Item Weight | 300 g | | Item model number | Pro-5 | | Manufacturer | Jackloc | | Material | Alloy Steel, Aluminium | | Number of Pieces | 1 | | Part Number | JACKBLK | | Special Features | Key Unlock | | Style | Modern | ## Product Details - **Brand:** Jackloc - **Lock type:** Key Lock - **Material:** Alloy Steel, Aluminium - **Special feature:** Key Unlock - **Style:** Modern ## Images ![Jackloc Window and Door Restrictor Black - Image 1](https://m.media-amazon.com/images/I/21FP4ymXGpL.jpg) ![Jackloc Window and Door Restrictor Black - Image 2](https://m.media-amazon.com/images/I/31EiDrsPFPL.jpg) ![Jackloc Window and Door Restrictor Black - Image 3](https://m.media-amazon.com/images/I/31bl4Ws5-DL.jpg) ![Jackloc Window and Door Restrictor Black - Image 4](https://m.media-amazon.com/images/I/41YhmrZttAL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ excellent *by T***M on 20 May 2014* I feel so happy that the windows are secure and safe.
