Replacement B&B Slide-Out Corner Cap for 2011 Montana 5th Wheel 3500RK

Updated 01/12/2025 | Published 12/10/2024

Question:

I have a 2011 Montana 5th wheel camper 3500RK. I am looking for slide out square corners from B and B Molding. Mine measures 4-15/16” and is white with a “700” number on the back. I saw you sell some of these. Would you have this one? Thanks for your help. Stan

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.

Thanks for helping Robin. It is slightly less than 5”. How do I send you a picture as I could not paste it here? Could I send those to your email? I looks just like the one on the page I sent it from below. I was hoping the “700” on the back of mine would help identify size and color.

@StanK sorry if it wasn't clear, you can respond to the email that brought you to this answer page and attach your pictures. The 700 is just the series of parts but they have a few variations so I wanted to gather as much information as possible before I try to get B&B to identify it and give us the replacement part number. Also, I'm not going to lie to you I read that as 4-5/16" earlier this morning and not 15/16. They have a 5" version as well, which we don't currently carry, so that sounds like the closest one. After that it is the 4-3/4" or 5-1/8" # BM33ZR. I'm sure the 5-1/8" would fit just fine but the holes might not line up. I'll go ahead reach out to B&B and get the part numbers for the 5" version.

@StanK I just talked to B&B and they said it is the 4-3/4" version so the BM78ZR above is the correct replacement.

@RobinH Does it come in different colors? Mine is white but there can be different versions of white and after 13 years it’s somewhat difficult to tell. Thanks Robin.

@Terry we don't carry any that are that small. You can either install larger ones or check with a local RV repair shop to see if they have some that match your measurement.
