Hellermanntyton TSR3FW-33-1 Raceway Internal Corner Cover

Product Description

The HELLERMANNTYTON TSR3FW-33-1 is an internal corner cover designed for use with surface-mount raceway systems. It provides a finished, protective transition at inside corners where raceway changes direction with a single bend radius. The cover fits raceway channels with a 1-3/4 inch channel width and is sold individually. Electricians and low-voltage installers use this fitting to complete raceway runs cleanly at interior wall corners, maintaining wire protection and a professional appearance throughout the installation.

This internal corner cover is used in surface raceway wiring installations for commercial and residential applications. It is typically installed at inside wall corners where the raceway transitions from one wall surface to an adjacent wall. The fitting maintains continuous cable management and protects conductors at direction changes. It is commonly used in retrofit wiring projects, office buildouts, and equipment installations where open cabling is not acceptable.

Key Features

• Internal corner design for inside-wall raceway direction changes
• Single bend radius geometry for smooth cable routing
• 1-3/4 inch channel width matches corresponding TSR series raceway base and cover
• Sold individually for precise quantity purchasing

Compatibility

Designed as an OEM-style fitting for surface-mount raceway systems accepting a 1-3/4 inch internal corner cover component. Confirm channel width and raceway series before ordering.

Installation Notes

Installation is performed by licensed electricians or low-voltage technicians as part of a complete surface raceway system. De-energize all circuits in the raceway before disassembling or modifying any section. Align the cover fitting squarely at the inside corner and press firmly until seated against the raceway base. Follow NEC Article 386 requirements for surface metal or nonmetallic raceways as applicable to the installation.
