018-341 EK RV Slide Out Seal Base 1/2 in x 2.75 in x 35 ft - Durable

In this review the 018-341 EK Slide Out Seal Base is evaluated for RV owners who need a reliable replacement or upgrade for a worn slideout seal. The bottom line: this base delivers a simple, durable channel for a D-seal to slide into and provides a neat, protective edge when the slideout is extended. It is best for DIYers and maintenance-minded RVers who want a long-length solution with an adhesive backing and the option to add fasteners, while those needing a complete rubber seal should remember the D-seal is purchased separately.

Key Features

• Full-length base: Comes in a continuous 35 ft length so a single run can cover most slideout perimeters without seams.
• Built-in wiper: The base integrates a wiper element that helps keep the mating surface clean and supports a tighter seal when paired with a D-seal.
• Straight-edge alignment: A straight edge and adhesive backing make positioning and sticking the track straightforward, reducing installation time.
• UV-stabilized material: Contains UV inhibitors for longer life, helping resist sun degradation on exterior installations.
• Simple installation options: Can be installed using the included adhesive backing or with fasteners for extra security in high-stress areas.
• Interior protection use: The EK Series may also be mounted on interior walls to protect the RV wall when the slideout is extended.

Who It's For

The base is aimed at RV owners replacing worn slideout channels or upgrading to a two-part EK system where a D-seal slides onto the base; it suits DIYers who prefer a product that can be applied with adhesive and optionally screwed down. It is especially useful for those who need a long continuous length and want a clean, straight alignment during installation.

It is not a complete seal by itself for buyers expecting a finished rubber edge out of the box, since the D-seal is sold separately. Customers who need custom-sized sections rather than a long roll or who want a pre-attached rubber lip should look for integrated one-piece seals instead.

Pros & Cons

Pros

• Long 35 ft length reduces seams and simplifies full-perimeter installs.
• Adhesive backing plus fastener option gives flexible installation methods.
• UV inhibitors extend outdoor life compared with untreated materials.
• Wiper and straight-edge design improve alignment and sealing when used with the D-seal.

Cons

• Adhesive quality gets mixed feedback, so additional fasteners may be needed in some situations.
• Does not include the D-seal, so a separate purchase is required for a complete rubber seal.
