SuperDi Pool Liner Lock Roll 120ft T-Shape PVC Beaded Wedge — White, Flexible Secure Grip

SuperDi Plastic 120ft T-Shape Pool Liner Lock Roll (QP1562) is a flexible, weather-resistant PVC beaded wedge designed to secure inground and above-ground pool liners with a tight, reusable T-shaped fit.

This 120-foot roll provides a cost-effective, long-length solution for fastening loose or replaced pool liners. Made from soft but durable PVC, the T-shaped profile slides into the liner gap and locks with three barb rows, offering a secure hold while remaining removable for maintenance or liner changes. The white finish gives a clean look that blends with most pool designs and helps hide dirt between routine cleanings.

How does this liner lock keep my pool liner in place?

The T-shaped cross-section and three staggered barb rows bite into the liner pocket and track, creating mechanical resistance that prevents the liner from pulling free under tension. Because the material is slightly flexible, it conforms to corners and irregularities for continuous contact.

• T-shaped dimensions: 7mm wide, 11mm tall, 8.5mm embedded height
• Three barb rows for secure grip
• Flexible PVC adapts to curves and corners
• 120ft length covers large perimeters without splicing

Is installation difficult and what tools do I need?

Installation can be completed by hand for short runs, and a few basic tools speed the process and ensure a snug fit. A small wooden block and hammer or a specialized pool liner lock tool help press the wedge evenly into the track without damaging the liner.

• Hand-installable for quick fixes
• Use hammer plus wooden block for even pressure
• Optional liner lock tool for faster, consistent results
• Removable and reusable for future liner replacement

Will this liner lock work for both inground and above-ground pools?

Yes — the SuperDi T-shape roll is designed to fit most beaded and standard liner tracks used in inground and above-ground pools. Its flexible material and thin profile make it an adaptable option for corners, slopes, and different coping setups.

• Compatible with beaded liners and many track systems
• Flexible for corner and irregular shapes
• Functions as coping strip or liner clip alternative
• Classic white color matches various pool styles

How does this product save money over other fixes?

A 120ft roll reduces the need for repeated short strips or costly professional repairs by covering large sections in a single piece. Because it’s reusable, future liner removals and re-installs don’t require replacement parts each time.

• 120ft continuous length minimizes seams and waste
• Durable PVC lowers replacement frequency
• Reusable for multiple liner changes or repairs
• Lightweight for easy storage and transport

Who is this for: Pool owners, maintenance professionals, and DIYers who need a reliable, economical solution to secure pool liners—especially those managing larger perimeters or planning future liner replacements. If you want an adaptable white liner lock that fits corners, works with beaded liners, and installs without specialized skills, the SuperDi 120ft T-Shape Roll (MPN: QP1562) is built for that purpose.
