ZK 30x30 Square Tube End Cap Polyethylene Black Adaptive Lamella Fitting

Product Overview

Zaślepka kwadratowa ZK 30x30 is a polyethylene end cap designed to finish and protect the open ends of 30x30 mm square tubes and profiles, used widely in furniture manufacturing, construction, and industrial assembly. The product is injection-molded and features a textured surface, which minimizes visible scratching during transport and bulk storage, making it suitable for OEM and professional installations in varied environments.

The differentiated feature of the ZK 30x30 model is its adaptive lamella insert design, which allows secure and durable fitting regardless of the wall thickness of the profile. This flexibility reduces procurement risk and inventory complexity, as the same SKU fits a range of material gauges without requiring multiple component sizes. It is particularly suited for bulk supply to furniture OEMs, construction contractors, and metalworking workshops requiring reliable, aesthetic tube end protection.
