JCJ ENTERPRJCJ M-800 Mud Dauber Furnace Screen

This screen is made much better than the Camco option. It is truly stainless steel, and had not rusted after one winter and a entire season of camping, nor has it clogged like the competitions' products. It covers the vent fully with the provided springs. They attach to the screen on either end, and then into the furnace vent, with the provided tool. It is a bit tricky to get it secured, so be patient. Once secured, it looks as if it may fall off easily. Believe it is on there! Proven by traveling with it on up and down the East Coast. It keeps the critters and bugs out effectively as well. I would recommend this product to everyone who owns an RV, and does not want wasps, mice, ect taking up residence in their unit! It is a must for all RV owners. Happy Camping!P.S. Make sure you keep the tool it comes with handy, in case you need to remove it.

Good quality; tricky to install. I am impressed with the quality of the stainless screen material. It hasn't rusted a bit after a year, It comes with a special little tool to help you hook the holding springs in place, but bring your patience. It could take you 15 minutes or more to get it hooked right.

Kept out the bugs

This is basically the same one that was sold at the RV place where I bought my trailer. It is simple to attach and seems to work well as it has been on for two years, isn't rusting and still on just as solid as day one.

Fits fine would be a five star if it was easier to attach springs.

It was what I was looking for didn't use as intended. Tbhanks

Works as advertised
