Surplus split set washers. Surface rusting but can be cleaned and reused.

Description:

Split Sets are rock bolts with only 2 parts, a tube and matching domed bearing plate. The high strength steel tube is slotted along its length. One end is tapered for easy insertion into a drill hole and the other has a welded ring flange to hold the bearing plate. With the bearing plate in place, the tube is driven into a slightly smaller hole, using the same standard percussion drill that made the hole. As the tube of the rock bolt slides into place, the full length of the slot narrows, causing radial pressure to be exerted against the rock over its full contact length.

Primary Uses:

• Ground Control
• Utility Hangers
  • Keep air hoses and water hoses off the ground and out of the roadway by hanging on side wall off a series of split set!
