Whirlwind WP2B/4QW Black Wall Plate, Four 1/4 in. Jacks

Whirlwind wall mounting plates are cover plates cut to fit standard electrical junction boxes, so they drop onto the box an electrician has already set rather than needing their own enclosure. Single gang plates are 4-1/2 by 2-3/4 in. and double gang are 4-1/2 by 4-1/2 in., with blank plates stocked up to 7 gang.

This one is the black aluminium, 2 gang, 4 Whirlwind WCQF 1/4 in. jacks. Whirlwind's standard plate thickness is 1/16 in.; the black and clear anodised finishes are also available in 1/8 in.
