Outwater 25 Foot White 3/4″ Center Barb Tee Moulding
Best for arcade cabinets, tables, and hobby projects that use 3/4″ thick panels. This flexible polyethylene T-molding contours to curved surfaces and features a center barb requiring a .065″ slot, tolerance up to .078″. It provides a solid, semi-gloss white color that resists rubbing off. Choose this if you have a 3/4″ panel and want a durable edge trim with a clean white finish. Caution: if your slot is wider, adding masking tape to the barb can improve fit.
Muzata Black 3/4 Inch Center Barb Tee Moulding
Best for projects needing a black 3/4″ edge trim on arcade machines or dark-finished tables. The package includes a 25 ft roll of flexible plastic T-molding with a center barb designed for 1/16″ slots. It’s easy to install by inserting into the slot, with a note that you can remove the interior U-section of the barb for corner applications. Caution: if the existing slot is too wide, use masking tape on the barb for a snug fit.
Outwater Plastic T-molding 1/2 Inch White
Best for smaller projects needing a 1/2″ panel fit. This T-molding uses center barb that requires a 0.065″ slot (tolerance up to 0.078″), with a semi-gloss white finish that won’t rub off. It’s made from tough polyethylene and conforms to curved surfaces. Choose this if your project uses 1/2″ thick panels or if you want a lighter trim option with color stability.

It’s suitable for DIY and professional settings, offering wear resistance and water tolerance. Caution: verify the edge thickness and slot compatibility for a secure fit, especially on curved edges.

This self-adhesive T-shaped transition strip is designed for tile to laminate floor transitions and other edge applications. The 300 cm length and 5 cm width provide coverage for larger gaps and varying edge shapes. Best for floor edging where a flexible, adhesive-backed solution is preferred. Caution: adhesion strength can vary with surface texture; ensure clean, dry surfaces before application.
Buying Guide
What panel thickness should I match?
Match the T-molding to your panel thickness for a secure fit. Common sizes are 1/2″, 3/4″, and 1″. Using a molding that’s too thick can create gaps, while too thin may slip out of place.
How do I size the slot or kerf?
Center barb trims require a specific slot width, often around 1/16″ or 0.065″. If your slot is wider, consider using masking tape on the barb to improve grip. For new installs, you can create a slot with appropriate width using a utility knife or router guided by the molding’s profile.
Is color important for visibility or aesthetics?
Color choice affects appearance and visibility. White trims blend with light panels and consoles; black trims create contrast on dark furniture or arcade cabinets. Durable, color-stable plastics resist rubbing or fading with use.
Can these trims be cut to length?
Yes. Most T-moldings are designed to be cut with ordinary scissors or a utility knife. For corner joints, removing a portion of the inner barb or using masking tape can help achieve clean transitions.
What about installation on curved surfaces?
Flexible polyethylene or PVC trims contour well to curved edges, reducing the risk of overhangs or gaps. For very tight curves, pre-bending the molding before seating it in the edge slot improves fit.
Adhesive versus mechanical fit?
Some trims rely solely on the barb and slot to hold in place; others may include, or benefit from, adhesive backing. Adhesives are useful on non-porous surfaces but may require surface preparation to maximize bonding strength.
