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.
