The brackets are for mounting an 8-socket Kopp POWERversal power strip to an Ikea Skadis board. Slide the brackets on both sides of the power strip, then screw them on the peg board using these T-nuts. The dimensions of the brackets are designed for the 8-socket version, a power strip with a different number of sockets may not conform to the 40mm raster of the peg board.
