An example of where slide bolts are used to great effect would be on double doors. You will often find them on the bottom and top of the door to keep it secure. They are an effective way to keep your home or office safe when not in use, as well as preventing certain corridors being used in public building like libraries, colleges and hospitals.
We at Hart Wholesale stock all of these and their accessories. So whatever kind of door you are working with we will have a suitable bolt that gets the job done.
