The Arke space saving line of stair kits include the Nice2, Karina and Oak 30.Xtra. They are ideal to use as a replacement for traditional pull-down attic stairs when converting an attic into a loft, office or bedroom. The system is composed of a set of prefabricated components (steps, modules, railing, balusters, etc.) assembled together to form a winder staircase. The steel load-bearing structure is manufactured in modules, one per step. Each module consists of 3 different pieces welded together, two of which are embossed metal sheets and the third consists of a 3-5/32-in x 1/8-in 3 diameter tube. When the kit is assembled, each module is fastened to the adjacent modules by means of screws and nuts. The Oak 30.Xtra is available in hi-gloss black and white powder-coated steel with oak wood treads with a protective polyurethane coating. The alternating tread design (right-step/left-step) allows for interior installation in very limited spaces. It can be installed straight and with one gradual L curve. Each space saving stair includes two specific modules, one bottom module for the structural attachment to the floor and one top module for the attachment of the staircase to the wall or to the upper floor. The railing is made of 25/32-in steel vertical balusters and five 1/16-in PVC tubes attached horizontally to the balusters. Add risers, additional handrails, second side rails, balcony rail kits and safety bars to reduce the space between the treads are available for optional purchase. Arke staircase kits 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 US 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.
