Double Arming Bolt

Double arming bolts are used in double crossarm construction to secure and lock in the spacing between the wooden crossarms. Double arming bolts are fully threaded to offer a wider range of adjustment for the crossarms, as well as the ability to fasten additional components or wooden members by simply adding additional hardware within the body of the bolt. Double arming bolts are normally supplied with four square nuts assembled and each end has a semi-cone point added for easy field installation. The length call-out does not include the semi-cone point ends.

Double End Bolt

Double-end bolts are used in double crossarm construction to secure and lock in the spacing between the wooden crossarms. Although the length of double end bolts varies and the documented thread length required is 3″ on each end, the thread on each end is commonly required to be 6″. Double-end bolts are typically supplied with two square nuts assembled and each end has a semi-cone point added for easy field installation. The length call-out does not include the semi-cone point ends.

Clamp Rod

Clamp rods are used as a center clamp for tying two wooden beams in an “x-brace” configuration. Clamp rod lengths are normally called out between the shoulders and they have approximately 1-1/4″ of thread on each end. Semi-cone points are not added to the ends of clamp rods.
