Cory, I'm quite certain they will fit, in terms of being the right length. I think the holes on the side will be the problem. I don't know if they will match up exactly. If they do, the holes will be much too big for the celcon stanchions. As Bob said, and I agree, the celcon handrails, while they look nice, don't stand up to handling very well. If I was going to change out BB handrails to celcon, I would fill all the existing holes with putty, sand them down, and then drill new holes that are the right size for the celcon handrails. At least a small touch of CA will then secure them. You're going to need gobs of CA to keep those little celcon tabs in the big BB holes.
