Full Product Overview
The Columbus Junior Aluminium Concertina Loft Ladder is a compact and highly practical loft access solution designed specifically for installations where headroom, loft clearance or swing space is restricted.
Unlike traditional folding loft ladders that require forward swing clearance, the Columbus Junior operates using a vertical concertina mechanism that extends smoothly downward while remaining compact within the opening area. This makes it ideal for narrow hallways, tight loft spaces, restricted landings and properties where conventional loft ladders are unsuitable.
Manufactured from durable die-cast aluminium, the ladder combines lightweight handling with dependable structural strength for frequent domestic and light commercial use. The integrated spring-assisted system ensures controlled, effortless deployment and smooth retraction, helping improve day-to-day usability and reducing strain during operation.
Wide 350 mm anti-slip treads with a generous 140 mm depth provide secure and comfortable footing while climbing, and the supplied timber backboard simplifies installation directly onto existing hatchboxes or suitable masonry structures.
Available in four size configurations covering floor-to-loft heights up to approximately 3.39 m, the Columbus Junior range provides a flexible solution for a wide variety of domestic loft access requirements.
