AP Products EK Series Slide-Out Seal Base with 2-7/8" Wiper — Black 35' (1/2" x 3.66") for RVs

AP Products 018-316 is a black EK Series slide-out seal base with an integrated 2-7/8" wiper, supplied in a 35-foot length and sized 1/2" x 3.66" for RV and camper slide-out protection.

This EK Seal Base with Wiper is engineered for slide-out rooms and edge protection on RVs, campers and motorhomes. The base ships with an attached wiper blade and a straight-edged backing for precise adhesive alignment; a D-seal (sold separately) slides onto the base to conceal fasteners and create a robust seal. Installers can rely on the adhesive backing for a quick bond or add mechanical fasteners for extra security. The profile measures 1/2" thick by 3.66" high and arrives in a 35-foot coil to cover full-length slide-out perimeters or long repair runs.

How does the EK Seal Base improve slide-out sealing and protection?

The base provides a stable track for a separate D-style rubber seal to slide onto, offering a tidy finished edge and improved weather resistance. The integrated wiper reduces dirt and abrasion where the moving slide meets the fixed body, helping extend the life of the rubber seal.

• Straight edge design for accurate adhesive placement
• Included 2-7/8" wiper cleans and cushions slide-out contact
• Accommodates D-seal that hides fasteners and reinforces the seal
• Durable profile sized for common RV slide-out gaps (1/2" x 3.66")

What are the installation options and best practices?

You can install the base using its adhesive backing for fast, clean application or use mechanical fasteners where extra hold is needed. Align the straight edge carefully, peel the backing, press into place and then slide the D-seal onto the track to complete the installation.

• Cut the 35' length to fit each slide-out run
• Use adhesive plus screws in high-stress locations for security
• Ensure mating surfaces are clean and dry before bonding
• Slip the D-seal onto the base after securing the track

Will this part work for repairs or full replacements?

The EK Base is designed for both fresh installations and retrofits when rubber seals are worn or damaged. Because it is sold as the base with wiper, you can replace only the worn D-seal or install the full system for a comprehensive refresh of the slide-out perimeter.

• Suitable for replacing aged or torn slide-out seals
• Compatible with matching D-seals (sold separately)
• 35' length covers many full-sized slide-outs or multiple smaller repairs
• Black finish integrates with common RV exteriors

What are the product dimensions and material features?

The profile is half an inch thick, 3.66 inches tall, and supplied in a continuous 35-foot length to fit typical slide-out assemblies. The base includes an integrated wiper and is shaped with a straight edge for reliable adhesive bonding and simple alignment.

• Dimensions: 0.5" (thickness) x 3.66" (height) x 35' (length)
• Color: black for discreet appearance
• Includes a 2-7/8" wiper blade for contact protection
• Designed to accept a D-seal that conceals fasteners

Who is this for: AP Products 018-316 suits RV owners, repair shops and DIY installers who need a reliable slide-out track base with an integrated wiper. Choose this part if you want a versatile base for new installations, a durable option for upgrading tired seals, or a long 35-foot run to cover extended slide-out perimeters. If you need the rubber D-seal that completes the weatherproof barrier, order it separately to pair with this EK base.
