25 Ft White 3/4″ Flexible T-Molding Trim
This flexible PVC T-molding is designed for 3/4″ edge slots and works well on arcade machines, game tables, shelves, and cabinets. The center barb profile provides a secure hold in a 1/16″ slot, with a curved surface for a snug fit. It’s easy to cut to size and install with a rubber mallet for best results. Best for DIYers who want a simple, durable edge around plywood, veneers, and tabletop panels.
Best for: DIY cabinet builders and arcade hobbyists seeking a lightweight, affordable edge trim. Better for: applications where a flexible, soft PVC edge is preferred. Choose this if: you need a long run (25 ft) in white for seamless coverage. Caution: ensure a 1/16″ slot is present or can be created for the barb to grip securely.
Outwater 25 Ft White 3/4″ Center Barb Tee Moulding
This 3/4″ center-barb tee molding is made for tough, flexible polyethylene that contours to curved surfaces. It’s ideal for edging countertops, desks, and arcade-game trims. The product is color-stable in vivid white, ensuring the edge remains bright over time. Best for: hobbyists who need a versatile, durable edge for rounded or irregular panels. Better for: projects where a solid white color resists rub-off. Caution: spacing must fit a .065″ to .078″ slot to ensure snug fit; consider masking tape to adjust fit if the slot is slightly oversized.
Outwater 25 Ft Black 3/4″ Center Barb Tee Moulding
This black version provides a sharp contrast on light surfaces and hides minor edge imperfections. It uses tough, flexible polyethylene to conform to curved surfaces and includes a center barb requiring a precise slot (around .065″ to .078″). Best for: people updating dark interiors or devices where hidden edges look cleaner. Better for: applications where color matching with black hardware is important. Caution: ensure slot integrity; a loose fit can loosen over time if the barb does not grip correctly.
1″ RV Trim Molding Insert
Made from premium TPE, this trim is softer and more flexible than vinyl, with high durability and heat resistance. It’s designed to fit many RV exteriors, camper shells, and travel trailers, and can be cut to size and installed without special tools. Best for: RV owners seeking a weather-resistant, flexible exterior trim. Better for: those who want a screw-cover style fit without adhesives. Caution: verify fit with your vehicle’s edge slots, as incorrect sizing can prevent proper insertion into existing channels.
Outwater 1/2″ White Flexible T-Molding
This 1/2″ molding fits smaller edge work on tables, desks, or shelves. It features a center barb designed for tight, secure installation in a narrow slot, and is colored semi-gloss white to prevent rub-off. Best for: smaller edge projects or lighter-duty RV interiors where a delicate finish is preferred. Better for: lighter panels that don’t require the heft of 3/4″ edging. Caution: slot width must be precise for a secure grip; otherwise consider pre-fitting with masking tape or a snug-fit approach.
Buying Guide
What edge size do you need? Measure the existing slot or edge thickness to choose 1/2″, 3/4″, or 1″ options. Flexible polyethylene or PVC affects durability and contour; choose polyethylene for curved surfaces and heavier-duty use, or PVC for lighter, flexible edges in arcade layouts.
What color matters? White edges blend with bright RV interiors, while black or dark shades hide imperfections and complement dark hardware. Consider a color that resists rub-off and matches surrounding trim.
Is installation easy? Look for center barb designs that fit standard .065″ to .078″ slots. If your slot is larger, masking tape can help secure the barb, but ensure a snug fit to prevent loosening over time.
Project scope and lifespan matter. For long runs along cabinets or arcade machines, select durable materials and longer lengths (25 ft coils) to minimize joints. For smaller, temporary, or decorative edges, 1/2″ or 1″ trims provide flexibility in cutting and mounting.
Do you need color stability? Some products are dyed solid to prevent rub-off. If the edge will be frequently rubbed by hands or equipment, color stability is essential to maintain a clean appearance over time.
