Plates, Crossarm Reinforcing

Reinforcing plates prevent damage to the crossarm from tightened nuts. Nos. 4045 and 4047 have a pressed rib and are normally used on the side of the crossarm to prevent the tightened nut from causing checking or splitting. No. 4063 is used on top or bottom of flat-top crossarms to impede the strain from forged steel pins.
