## Description

Black Rubber is the ultimate Slide Out Seal Systems. Can be used for new installations or when upgrading worn out rubber seals. Order in two parts. Base is designed with straight edge for easy alignment w/adhesive backing. Fasteners maybe used to install as well. D Seal, purchased separately, easily slides onto track in base, hides fasteners and provides a positive seal. Black Rubber may also be used on interior wall for protection when Slide Out Room is extended or, when replacing a double seal. Dimensions: 1" x 15/16" x 35

Review: Perfect replacement and easy to install. - Easy installation! I removed the 17 year old seal and this simply slides right back into the original track. However, a little trick when sliding 12 foot across the top. I found that at first it would slide on easy until you would get about 3 foot on and then it would be to much friction to continue. So I sprayed WD40 onto the track ( one more use for WD40 !) and it slide on easy ! Other than the friction issue, which is not the seals issue, it is durable, well made, and should last at least another 17 years!
Review: Good product - I was dreading replacing my slide 'bubble' seal that was falling apart. A local repair shop wanted twice the price for a replacement seal. This was an exact fit. VERY easy to install (removing the old seal was messy, but easier than I thought it would be) Looks great .... seems to seal as it should ...... good product.

### ⭐⭐⭐⭐⭐ Easy replacement
*by J***F on April 11, 2022*

Fits well. Works as well as original seal. The “D” seals on my RV, seem to need replacing more often than the rest of the seals. Even when new, the material is sticky, presumably so that the seal is better around the slide outs, which causes it to eventually begin tearing when the slides are moved out. May try adding a flat, thin Teflon (or any) non-stick surface to oppose the D seal so that the release is better which may help increase the time between replacement.
