We've decided to put a cable rail type stair banister inside between the main and lower floor. After a bit of research on where to get the components, we narrowed it down to Ultra-tec out of Carson City, Nevada (www.ultra-tec.com)
The code here is the maximum distance between cables is 4". We will need 7 cables running down each section. The cables usually come with one end already assembled (called "swaged") on that has a tension adjusting bolt/receiver combo. The other end usually gets a field installed self gripping receiver.
Ultra-tec has a nice product line. The can make custom cable runs in any specified length and can "swager" the tensioner on the one end for you. We're using 3/16" cable. For each cable, we need a swaged threaded stud and Invisiware Receiver for one end, a push lock fitting for the other. We will also add grommets in each post to make a nice finished look. We're also getting a grommet tool from them to properly install the grommets. Brian our builder will use a high speed wheel to cut the cables to exact length.
I asked about the tools necessary to do the swagering ourselves but these are pretty expensive, about $3K for the air tool swager end and air over hydraulic pump. We could rent them from Ultra-tec but again this is overkill. Maybe if were building a lot of these it would be worth it.
We are having the posts custom welded by one of Brian's contacts and plan to have them powder coated in "penny" color. I'll post pictures when it's done.
