Customer Questions & Answers

questions about extensions, coating, code compliance

if one needs to extend the stair to 135 inches, do you need one or two extra steps? Would the PVC handrail be long enough? What about the length of the main post? does the powder coating hold up just as well as galvanized for outdoor use? is this the smallest width stair that meets the building code (does it even meet code)?
Asked by: Steve
To extend the height to the noted 135", you would need to purchase 2 additional stair treads PLUS 2 32" center poles. One of these 32" center poles would be used in replacement of one of the 48" center poles included in the standard kit. The handrail coil included in the standard kit is enough to complete the installation to the extended height. The 63" diameter model will meet the current IRC building code requirements as relates to spiral staircases. We would recommend if you are near the coast that you purchase the Enduro Steel model which is more resistant to the harsher environmental elements of the coastal regions with high salt air content. The powder coat finish is very good for other regions with less harsh conditions and has performed extremely well.

What do you mean, "Tread cover adhesive for exterior installation not included." What is that? Is it needed?
Asked by: Mike
Mike....there is a 2-sided tape included for interior installations. However, for exterior installations we recommend a silicone adhesive to attach the tread covers to the stair treads. We recommend that you purchase a silicone adhesive that will bond plastic and metal parts. This can be found in the paint department of major DIY hardware stores. Further, from experience, we recommend you use a light weight sandpaper and "rough" the bottom surface of each tread cover to provide a better "bite" of the adhesive on the surface of the tread cover. Apply the adhesive in a "S" pattern, place the cover on the tread and then place a weighted object on the tread cover and allow to sit for 2 hours to get a tight bond of the adhesive to the cover and tread. Should you have further questions, please contact our Customer Sales & Support team via our toll free telephone number at (888) 782-4758 and our team will be happy to assist.
