EXTENSION BOLTS AND STRAPS

Multiple

Reduce your pole space requirements and installation labor demands with GMP’s Extension Bolts and Reinforcing Straps.

  • These versatile, galvanized steel bolts let you place a second messenger at the same level and on the same side of a pole as an existing messenger.
  • Each bolt attaches to the threaded end of a suspension bolt already in the pole.
  • We offer bolts in two thread sizes: 5/8 in.-11 and 3/4 in.-10. Both are available in 7 in. (178mm) overall length which yields a 4 in. (101mm) offset extension.
  • The 5/8 in. size is also offered in an 11 in. (279mm) length which gives an extension of 8 in. (203mm). The longer bolt makes it easier to lash as the lasher works near the pole. Installation is easy.
