Keeping Mice Out

Been working on sealing up any openings in the underside of the trailer that mice could use to get in. I've sealed up numerous gaps between the frame and the coroplast panel. I still have two openings in the I-beams where I'm fairly sure that mice have been getting in and I need ideas for preventing entry.

The left and right side I-beams each have one oval hole (about 3" x 1.5") where the slide-out's hydraulic actuator rod passes thru. I've been plugging up the gap with steel wool wrapped in a dryer sheet each time we put the slides out and whenever I put the unit in storage. This works, but I'm getting tired of the procedure and am looking for a permanent solution.

I've been thinking of a boot-like cover that, at one end, would attach around the hole with velcro, and have a hole in the center of the other end for the rod to pass thru. Maybe made out of rubber or leather.

I can't use a rigid plate with a hole in it because the rod's position relative to the sides of the hole is different when the slide is in compared to when it is out. (The rod needs to be able to move up/down and left/right in the opening as the slide is actuated.)

I've spoken with Crossroads as well as Lippert, but they had no ideas. I thought that maybe a higher-end trailer might come with an appropriate cover for the opening, but apparently not so.

Has anyone come up with a solution to this problem?

    I gave up searching online before posting, but I did follow your suggestion and tried Grainger.com, but no luck. I think I need some sort of DIY solution.

    I checked the reviews on Amazon (3 stars) - not exactly an endorsement.
    Also, they require 110 volts which I don't have at my storage yard nor when I'm dry camping.
