Wire Rope Insulation & Welding Accessories
Compliant with North American Standards
Spider’s wire rope insulation and welding accessories provide critical safety protection when performing welding from a suspended basket or platform.
- Insulated thimble assemblies isolate the wire rope to protect rigging and structural components above.
- Arc guard protects the wire rope above and below fair lead and below deck to prevent accidental severing of the wire while welding.
