TheD-D Jumpguard Flexi-cutout Set provides you with 2 standard corners and 2 reverse corners to allow you to modify the frame around any larger overflow boxes, light brackets, cables or pipework etc, that would not be covered by the Multi-Cutout Set. Each kit contains

• 1 pair of standard corners 
• 1 pair of reverse corners

Note:Cutting into the standard square frame, especially on larger frames, will generally reduce the rigidity and we would recommend installing one of one or more cross braces, as required, to retain the structural integrity.
