Relay boxes complete with transparent cover, gasket and locking bars. Supplied with terminals for crimping cables 1.0mm² to 2.5mm². The female push-on terminals provided are crimped onto the cables and are inserted underneath the relay box and are firmly held in place using the locking pieces. Both boxes can be clipped together along with the 16 way fuse box (FBB16U) to form a single integrated unit that is infinitely variable to suit almost every requirement. Individually packed.
