Metal Insulated Attic Ladder - Various Sizes
LWM Series
The LWM attic ladder is a folding metal attic
ladder, supplied with an insulated hatch door. The door is beige on the inside
and outside. Allowed maximum load of the metal ladder is 440lb, but during the
laboratory tests, no visible deformations of the ladder were observed under the
load of 1330 lb.
The 1 1/16" thick, heat-insulating hatch significantly reduces heat loss. A
peripheral seal positioned in the milled part of the box provides a first-class
tightness.
The ladder's segment folding system and possibility to lock the hatch in fully
open position ensure an ease of operating. The double hinges' joints and
stringer's profile plugging guarantee high ladder's durability. The patented
hatch hinge's corner prevents frame deformation. The visible side of the hatch
is smooth.
