@@ralphsarc1471 Thanks. Each slide typically has four rails/racks so you would need 8 to upgrade the whole system. You also need to know what style of end brackets your RV uses. Typically notched brackets are used on the outside and flat on the inside, but each RV is different.

I have the same system but commercial, purchased from eSun, where you get reusable zip-lock vacuum bags.

So do I, and it works great.​@@Mr-J...

That's why you make it a little bit longer on the end. So when you cut it, you just cut the tip of that and open it and then you reseal it again cuz you had extra length

@@MrPancake0825 thanks for the question! The aluminum end bracket is going to be hard anodized that will break the possible conductivity between the nickel plated rail end and stainless screws/springs. The other possible areas are between the nickel plated rail end and the anodized Lippert rail and the stainless pins. Nickel is the less noble metal, so that would be the first after many years to show signs of corrosion, but because the surface area is so small, it is not a electrical part or submerged in salt water, the rest of the Lippert system will fail first. I will supply a small tube of dielectric grease to keep things lubricated which will also prevent corrosion. The parts will have a lifetime warranty, so the customer can request replacement if by remote chance any of this happens. Thanks for the great question!

Activated alumina is the least toxic and has more absorption power. The negative side is that it doesn't have a color indicator. Also alumina last longer, while silica is slowly destroyed after each regeneration

My spools spring back to shape

​@leeroykat6546 silica bags come free with almost everything these days. I always collect them and keep them stored in an air-tight container for my filament use.

@@boblousi5962 after annealing I seal the part with plastic spray paint. 👍

there should be 2 motors

Or maybe some type of alloy?

Coachmen seems to use steel rods with their side now for 2025's.

Also, love your video!!!!!

@@djhall5 thanks for all of the great comments. Yes, stainless steel or brass would be stronger, but it would be overkill as the whole mechanism is only as strong as the weakest member, and that is the Aluminum rack. It will break before anything else.

It is 10 x 14 x 0.5 inches. I own a CNC machine shop so I cut it from a plate of 1/2 AL. I can make you one or there are several online metal suppliers that can cut you a piece of metal and ship it for less cost.

@@joeb954 No, it is designed to repair a broken rail. The broken portion of the rail must be cut off. The block replaces the original pin mounting hole that was broken or cut off.

@@ralphsarc1471 Thanks for the comments! This is a repair kit for broken rails which requires cutting off the tip of the rail. I suggest holding off until the rail breaks. No need in making additional work for yourself. Don’t tell anyone, but I am currently working on a bolt on upgrade that doesn’t require cutting the rail. Shhhhhh :-)

@@briankinnear9386 thanks for the question. As mentioned in the video, I measured four different rails and all of them were different measurements tooth to mounting hole. I took the average. Lippert has a video on how to sync the motors/rails by opening and holding till clicks then closing and holding till it clicks. They designed so much clearance into the system. That’s the only way to get everything synchronized.

Vacuum Sealer Bags Rolls 11" x 16' ... Yes, Activated AL is the very best
