Sold in bags of 10 pieces, this is a must have accessory for Bang & Olufsen service or installation engineers. Designed to be placed over the standard IR transmitter, this cover will prevent the problem of the IR transmitter falling off 3rd party boxes and causing a "fault" within the B&O installation. The high strength, high temperature glue does not allow for repeat usage, once removed from the 3rd party box, the cover is no longer useable. The product is made from IR invisible plastic. This allows you to use the 3rd party product's original remote control during installation, because the Infra Red will pass through our 'IR Cover'
