The Zig Zag Concertina Loft Ladder is manufactured to EN14975 (DN4570) from die cast aluminium with two heavy duty counter-balanced springs incorporated into pivot brackets. With a huge maximum load of 200 kg per tread and a maximum ladder load of 500 kg/m2, it is a recommended second means of escape from plant rooms and industrial environments.
Telescopic handrail is available as an optional extra.
If the unit is to be fitted to a vertical surface greater than 400mm then a 50mm packer would be required so that when the stairway is in the stored close position it does not foul against the vertical wall. Therefore the minimum aperture length would need to be increased. When the stairway is fitted to a vertical surface greater than 400mm then an additional tread would be required.
We also offer a Lightweight Slimline Version of the Concertina Loft Ladder. More information on the differences of this ladder can be found here-
