Straight lines, screw or step-ladders

Stationary or developing ladders take not enough place and allow to rise confidently on an attic.

The ready standard ladders conducting on an attic are simple for installation. There are two types of similar ladders: stationary (built in) and developing.

Stationary ladders can have a screw or direct design and take not enough place. Without breaking an interior, they are easily entered in any lay-out and can be used even for apartments in two levels.

Developing ladders with system of hinges do not need a special support on a floor. Completed with a cover in tone to a ceiling, they become imperceptible in the combined kind. Such ladders can become fine alternative to ladders attached outside of summer residences.


Collapsible cleaned ladders

Consisting of three sections, step-ladders are made complete with a folding cover of the hatch from 19 mm of the joiner's plate finished under colour of a ceiling. Springs keep it in the combined condition in an aperture, and the simple and reliable mechanism without efforts opens. Then other two sections lean back, and the way on an attic is opened. Into the firm complete set enter the additional device against casual opening and a steel skeleton for the hatch with the raised fire resistance. The hatch from an attic equip additional folding dverkoj with the thermal protection closing a ladder in the combined condition.

Two-section sliding ladders

The design of such ladders consists of the bottom longer section and top. At ladder folding the bottom section moves on top, built in in a folding cover of the hatch. The bottom section, length about metre, defines the size of the hatch on an attic. Such firm ladders are equipped with adjustable hinges and the lock device with the strengthened spring. It allows without efforts to put and close a ladder. Latest models of such ladders have a protective handrail from a tree or aluminium and steel support.

Comfortable step-ladders

The step-ladders, which elements are cast from aluminium and have qualitative processing, are the most safe for lifting on an attic. Such designs have steps in width of 16 sm and the place for a turn do not demand. They open and closed almost silently. Thanks to good balancing the hatch and a ladder are easy-to-use. Steps in any position settle down horizontally and are not turned, and springs at the closed hatch are not strained. Ladders of such level can be built in a doorway with a door, providing normal pass.
