Gladon Premium Peel-and-Stick Above-Ground Pool Cove, 48-inch 17-Pack — High-Density Foam, Adhesive Backing

Gladon NL104-17 is a premium, peel-and-stick pool cove designed to sit along the inside base of above-ground pools to protect liners and reduce premature stretching.

When you replace a pool liner, installing a quality cove is one of the simplest upgrades that extends liner life and improves fit. The Gladon NL104-17 comes in 48-inch lengths with an adhesive backing for fast installation and is manufactured at a higher density to resist compression under water pressure. This 17-pack covers common pool sizes and is shaped to form a continuous radius at the junction of wall and floor, helping the liner lay smoothly and reducing stress where wear typically begins.

How does this cove protect my new pool liner?

By creating a rounded transition at the base of your pool wall, the Gladon cove prevents sharp bends and concentrated stretching in the liner material. That smoother curve spreads tension across a larger surface area, lowering the chance of tears and seam damage that occur where a flat floor meets a vertical wall. The higher density foam also resists long-term compression so the benefit lasts through seasons of use.

• Rounded profile reduces stress points at wall-floor junctions
• 1.8 lb/ft³ density minimizes internal air compression
• Peel-and-stick adhesive keeps cove seated during liner installation
• 48-inch lengths make continuous runs with fewer joints

Why is the material density important for pool cove?

Density controls how much the cove compresses under the weight of water. Low-density products contain more air and can flatten over time, which lets the liner pull against the wall and form stress lines. Gladon’s premium rating of 1.8 pounds per cubic foot reduces air content so the cove retains shape longer and maintains the radius the liner needs to rest properly.

• Higher density equals less compressible air inside the foam
• Stable profile prevents liner sagging and wall pull
• Rated to withstand routine water pressure in above-ground pools

How easy is installation for DIYers and installers?

Installation is straightforward: clean the pool wall and floor junction, peel the adhesive liner, and press each 48-inch piece into place. The pre-sized lengths and adhesive backing speed up the job compared with loose-fill options or foam that must be glued manually. For most above-ground liners, this cove is positioned before the liner is fitted and inflated, creating an immediate, continuous radius.

• Peel-and-stick backing simplifies placement and alignment
• 48-inch sections reduce the number of seams to manage
• 17-pack tailored to common 15'×25' oval and 21' round pool layouts

Will this cove fit my pool size and shape?

The 17-pack of 48-inch pieces is sized to form a continuous cove for many mid-size above-ground pools, including 15-ft x 25-ft oval pools and 21-ft round pools. Because the pieces are modular, you can join and trim sections to match irregular layouts or offset seams. Always plan seams to fall in less visible areas and verify needed footage before ordering to avoid shortfalls.

• Pack contains 17 pieces, each 48 inches long
• Typical coverage for 15'×25' oval and 21' round pools
• Sections can be trimmed to custom fit nonstandard shapes
