£423.00
The nVent HOFFMAN F66LA is a robust lay-in telescope fitting for industrial wireway systems, designed to provide an adjustable connection between compatible sections of nVent HOFFMAN lay-in wireway. With a nominal cross-section of 152 × 152 mm (6 × 6 in.), it provides a practical solution where the exact distance between wireway sections cannot be determined until installation.
As part of the nVent HOFFMAN F10 Lay-In NEMA Type 12 Wireway range, the F66LA allows its effective length to be adjusted from approximately 25 mm to 178 mm (1–7 in.). This telescoping arrangement eliminates the need to cut or weld the fitting to achieve the required installation length, helping reduce installation time while maintaining a professional wire-management system.
Manufactured from steel and finished in grey, the F66LA is designed for demanding industrial electrical installations. Its lay-in construction allows conductors to be placed into the wireway rather than pulled through the complete run, making installation and maintenance easier where numerous power, control or instrumentation cables need to be routed.
Industrial wireway installations often require small adjustments where sections meet enclosures, machinery or other wireway components. A telescope fitting provides an adjustable section that compensates for these dimensional differences without requiring installers to cut and weld a fixed-length fitting.
The nVent HOFFMAN F66LA can be adjusted between 25 mm and 178 mm, allowing installers to establish the required connection length on site. Combined with the lay-in wireway design, this provides convenient access to conductors and helps simplify the installation, inspection and modification of industrial cable-routing systems.
