"A good quality product from ERA a well known name for security products. Easily fitted with basic woodworking skills and will give peace of mind for a more secure door on the vulnerable hinge side. Hidden from view with the door closed and very unobtrusive when open. I have only maked the performance as good and not excellent as its not been tested. But there again I don't want it to be, but its fitted just in case someone decides to put it to the test!"
"These bolts are designed to prevent outward opening doors being removed from their hinges, although they provide protection against forced entry for inward opening doors too. I fitted these to an historic building because I am not able to install modern door furniture on the timber doors. Once installed these bolts are not visible and even when the door is open they are not unsightly. I would give them a 5* rating if the bolt fitted more snugly in the keep drilled in to the door frame, but I guess some free space has been allowed for seasonal movement and the door swing."
