E Craftsmen "Slim Line" LED lighting open-type step-down transformers can be provided with optional mounting brackets. This new configuration consists of a pair of plated steel brackets that a user can easily install themselves. The brackets simply slip over the core at either end and "contain" the transformer when the brackets are fastened-down to the lighting fixture by screws. Save significant cost by simply installing them yourself or alternatively, they can be shipped pre-installed from E Craftsmen for an additional cost. Click on the part number in the Slim Line table of parts for specifications for mounting centers.
