The original retractable ladder

Engineered to our highest standards by our own design bureau first in 1968, the lightweight 100% anodized aluminium JOMY Ladder can widthstand an incredible charge of up to 5,000 Kg (71 average weight adults)! It is the most robust retractable ladder on the market.

With JOMY's contemporary and refined design, architects and builders have an unobtrusive way of providing a reliable means of egress and access to their creations. With the looks of a slim downspout and available RAL color options, the JOMY vertical ladders will compliment every design.

With multiple independent opening handles, the JOMY foldout ladders are designed to perform on every level, at every level. With a one-hand smooth opening mechanism, they provide everyone with the reassurance needed in crucial moments like an emergency.

The use of marine grade anodized aluminium and a weatherproof box-section design garantees a year-long well-functioning ladder. Add a unique guardrail design, optional lifeline and a tamper-proof lockable mechanism and you are sure to have the best solution at hand.
