These Slipfitters are ultra-heavy-duty for the Compact Reach luminaire. They feature a T-bracket with two 1/2 stainless bolts to attach to the fixture yoke, and a wiring chamber with weatherproof gasket and cable gland for secure electrical connection. For additional safety, a 1/2 stainless steel bolt is provided to bolt through the pole top, for which the installer will be required to drill a clearance hole. An internal sleeve is provided to pack the slipfitter base for use with 2 3/8 Tenons.
