I am trying to locate a replacement part for the threshold/sill for the entry door on our older fifth wheel. I'm not sure exactly what it's called, so that's making it difficult for me to find any info.

The current part is aluminum and it fits over the inside lower edge of the door frame and extends out over the vinyl. From the side (profile), it looks like a small, square upside-down U and that's the part that hooks over the frame. Then it has a concave curve.

We can still use the old piece, but I'd really like to find one in a brushed/matte gold since we've replaced the floor with Allure plank.

If anyone can tell me what that part is called and also suggestions for where I might order one, I'd appreciate it. I don't think it's rare, but it may not be something that a lot of people have to replace.

Thanks,

liz

I would check Lowe's or Home Depot. They have lots of aluminum extrusions that are meant to be used to make transitions from carpet to tile or from tile to wood floor. A threshold would probably be wider, especially those for household use. I've seen the extrusions in silver, gold, and dark brown.

A sill is under a window. A door has a threshold (to hold in the "thress" or grass/wheatstocks that covered dirt floors in times of old) (like when I was a kid).

Dick:

So far, I've only found thresholds that had a hump in the middle and were tapered on either side but I'll keep looking.

Thanks for the explanation. I wish ours would keep the "thress" outside

Dick,

Actually, I think it is a sill. The threshold is in the door. This part transitions from the threshold to the vinyl. I found something on the Randall Manufacturing web site that is an oak and aluminum adjustable sill. It's not what I'm looking for, but I think I'm looking for a sill.

Whatever it is, it was probably part of the door assembly or added by the RV manufacturer. In other words, a custom component. You might be able to get a metal working shop to make something like it.

LibbyLA - I do stand corrected. A sill is "a horizonal piece forming the bottom frame of a door or window". While a threshold is "a piece of wood, stone, metal, etc. placed beneath a door; doorsill). So, I still think it is a threshold but could ask for a sill.

It should be available at any RV repair shop. Have you tried that? I doubt it will be available in gold, so you will have to have it anodized to your color choice. Or better yet, have it powdercoated. More durable and a near infinite choice of colors.
