Overview
The Hoffman F88LA telescope fitting lay-in is a critical component for modular wireway systems requiring field-adjustable connections. This NEMA 12–rated fitting enables electricians and system integrators to bridge variable distances between wireway sections without fabrication. The lay-in hinged-cover design with latched closure provides both structural integrity and accessibility.
Key Features
- Adjustable length: Extends from 1.00 inch to 7.00 inch, eliminating custom cutting and welding
- Hinged, latched cover: Provides secure closure and easy access to internal wireway components
- Complete assembly: Shipped with gaskets, screws, and sealing plates for ready-to-install operation
- Robust construction: 14 gauge steel body with 10 gauge steel flange for durability
- Corrosion-resistant finish: ANSI 61 gray polyester powder coating over phosphatized surface
