The Arke Oak 70.Xtra interior spiral staircase line of products consists of spiral staircase models, additional risers, handrails, center poles, matching balcony rails and safety bars. The Oak 70.Xtra spiral staircase kits are available in 51 and 63-in diameters and 2 colors - black, and white. The stair treads are manufactured from solid oak wood, finished with a light natural stain and clear coat protective sealer. Each standard stair kit includes 12 treads, 1 universal landing, balusters and horizontal tubing, handrails made of an aluminum core with a vinyl cover, landing rail and hardware. Each kit installs with a 360° turn. By adding or subtracting treads to achieve different heights the rotation will change by approximately 26 - 30° per tread. Safety bars – required by some municipalities - are available in a set of 12 to close off the back of the treads (creating a 4” maximum gap). Arke staircases can be easily installed by the homeowner in a single day using common household tools. A complete installation guide is included with all kits. Toll-free support is available (888) 782-4758. Consult your local building inspector for any questions and specifics regarding compliance with the local building codes prior to purchase.
