These brackets fit in pairs by interlocking inside the hinge rebate of a upvc window. Manufactured by Securistyle under the Vector brand, they are easy to fit brackets that provide security at a vulnerable area of the window. It is easy to forget that the hinge corner side of the window can be jemmied easily without this interlocking security system. Supplied as a set of 4 brackets for 2 positions on the window, for maximum brace, and including screws and instructions for easy installation.
