The Supreme heavy duty aluminium loft ladder is supplied as a ready to fit unit. It is manufactured from high strength die-cast aluminium alloy components contained within, and attached to, a laminated wooden hatch box and a 62mm thick sandwich construction insulated trapdoor. The Supreme therefore offers excellent thermal efficiency.
The heavy duty spring mechanism allows you to raise and lower the loft ladder with a minimum of effort (operating force of less than 3kg). In addition, large steps and pre-assembled telescopic handrail offer comfort, safety and ease of egress.
