(Patent No. 5,448,018) MacLean Power Systems Z-series Service Mast Wireholders are manufactured from an engineered blend of nylon alloy reinforced with fibers to provide approximately twice the fracture strength as porcelain. The durable nylon alloy material is U.V. stabilized for extended service life in ultraviolet exposure. The bracket design features an open slot which allows the bracket to be installed without disassembling the bolts. Accommodates a range of 1-1/4-inch through 3-inch diameter pipe. Dimensions of the nylon alloy insulator are the same as shown for the J089Z wireholders.
- Wireholder: Nylon Alloy
