The XL scissor stair extension can be used if the stair box is mounted in the suspended ceiling and there is a plenum that has to be bridged. The extension method used gives the stair two or more treads but the slope remains the same. This considerably increases safety because there is no need for hooks or treads installed vertically above each other.

 

Usage

The XL scissor stair extension is intended to be combined with the XL scissor stair. Other uses are not recommended. The construction and the material used guarantee a high level of stability and long-term safe usage.

 

Versions

The extension is available in versions with 2, 3 or 4 treads to span a plenum of 1,200 mm maximum.
