This steel wall penetration sleeve kit is designed for general electrical wiring installations.

It creates a clean, standardized opening for cables passing through walls.

The smooth inner surface effectively reduces friction, preventing cable abrasion while pulling wires through partitions.

The kit includes matching steel washers, sliding lock couplings and protective PVC bushings, enabling quick and simple on-site installation. It is a practical, cost-effective solution for electrical construction projects. 

Benefits:

Cost-effective solution for electrical wiring projects. 

Makes wall penetrations neat, clean, and organized. 

Smooth inner design allows cables to be pulled easily, even at a 45-degree angle. 

The sleeve acts as a guide, reducing friction during cable pulling and saving installation time.
