  • Replacement B&B Slide-Out Corner Cap for 2011 Montana 5th Wheel 3500RK
    Hi Stan; is it completely flat with 2 holes for screws? Or is it curved on the end like the # BM78ZR you were looking at? If you can send a picture as a response to the email with the link for this page that would help as well. It sounds like it may be one of their 4-1/4" versions which I could see about adding to our site but I need a little more information to identify it.

  • Distance Between Holes On B&B Square Corner Cap
    Hey Tim! Sorry for the delay, we're a bit behind. The holes on the B&B Square Corner Cap for RV Slide-Out # BM78ZR are 3-1/2" apart. Since it isn't some kind of weight bearing or structural part, I'm sure you can make it work with what you have. What kind of trailer are you working on?
