Product Information
Full details
The Stakkabox JMF104 duct access cover is a specialized solution designed for civil engineering and telecommunications professionals tasked with maintaining BT Quadbox systems. It offers the key benefit of a unique slide-out design, which enables a single technician to access the chamber safely and efficiently without heavy machinery. While this concrete cover is engineered for superior durability and compliance, users must ensure it is paired exclusively with the JMF104 BT Quadbox system, as it is not universal for all chamber dimensions.

Setup, Compatibility & Care
To install the JMF104, ensure the Quadbox chamber is perfectly level and cleared of debris. Place the guide rails securely on the chamber frame, ensuring the sliding mechanism is free of gravel or dirt. Lubricate the tracks lightly if necessary to maintain ease of movement. For long-term care, regularly inspect the sliding tracks to ensure they are free of mud, ice, or stones. If the cover becomes difficult to slide, clean the contact points with a pressure washer or brush, and check for any minor misalignment in the chamber frame.
