Access door RD 18 - SKK

Compact Galvanized Steel Access Door with Self-Adhesive Edge Protection for Safe Air Duct Inspection

The Revision RD SKK has been specifically designed for rectangular, non-insulated air ducts. It provides fast and safe access to inspection, cleaning and maintenance areas. The key advantage is the integrated self-adhesive edge protection (SKK) made of EPDM. It reliably covers cut edges, reduces the risk of injury and simultaneously contributes to the sealing of the inspection opening.

In daily operations, duct installers, service companies and facility operators are often faced with a common challenge. Inspection openings must remain permanently airtight, safe and easy to maintain. The Galvanized steel access door provides a practical solution. Its robust design with an inner and outer cover securely clamps the duct wall in place. Corrosion-resistant handles ensure convenient opening even after years of operation.
