SH Series zero space rackshelves feature full-depth front and rear rackmounting, providing a secure shelf for non-rackmount components. A truly unique design, these zero space shelves actually mount to the sides of the rackrail (not the threaded face) providing more useable shelf area and feature up to a robust 250 lb. weight capacity, depending on model. Two handy "L" brackets are included to help position equipment. Constructed from 16-gauge steel, includes mounting hardware, and is finished in a durable black powder coat.
