Product Overview

The Kompact model is available in 2 different size tread widths - a 29 in. model and a 35 in. model. Each of the two Kompact models can be configured into different shapes at installation with the L and U options available. It is available in 3 colors - black, white, and grey - powder coat finish painted-ready to install. The standard Kompact staircase kit is adjustable in height from a range of 7 ft. 4 in. to 9 ft. 11 in. and with additional components, can be extended to a maximum height of 12 ft. 2 in. The minimum height for this kit is 6 ft. 3 1/4 in. (here you simply use fewer treads). The Kompact comes with the internal handrail for one side. A second side handrail is available as an optional accessory. The Kompact stair treads are manufactured from European beech wood, finished with a light natural stain and clear coat protective sealer. Riser bars are available in a set of 11 to close off the back of the treads. To complete your project a balcony rail kit is available.

Customer Questions & Answers

Is this compliant with the International Residential Code (IRC).

Please list all the modular and spiral stair sizes that meet the IRC.
Asked by: Thomas
The KOMPACT staircase kit will not meet the multiple definition requirements of the current IRC code. However, not all installations require the project to be approved by a local building inspector as it depends on the specific municipality that you live and their specific requirements regarding "secondary" egress of the area. Please contact our Customer Sales & Support Team at and we can email specific information on the KOMPACT that you can take to your local building inspector for their review.

Can this be used out door too?

Asked by: Lauralee
The Kompact staircase kit is not recommended for exterior installation as it does not have marine grade stainless steel hardware and the light weight polyurethane protective coating on the stair treads is not formulated to withstand the exterior environmental conditions.

Depth of treads

What are the depths of the stair treads (runs)?
Asked by: Nat
The KOMPACT model is actually adjustable in both the rise and run based on the needs of your installation. Please contact our Customer Sales & Support team via our toll free telephone number at (888) 782-4758 and our team can send you more detailed information for your review and consideration.
