Outwater 1936-Bk Black 1 X 1 Angled Moulding

Features include 1″ x 1″ even legs and an 85 to 90 degree angle. Best for protecting small furniture edges and corners from impact without visible scratches. Suitable for light-duty applications in home offices, desks, and display units. The moulding provides a clean, unobtrusive finish that blends with dark finishes due to its black styling.
Best for: small edge protection on furniture where a discrete appearance matters. Choose this if you need a compact, uniform corner trim that hides minor impacts.
Caution: The rigid styrene may be less forgiving on curved surfaces or irregular profiles; ensure the edge is relatively flat before installation.
EYAYEN Wall Corner Protector Moulding

Features emphasize versatile angle adjustment from 90 to 180 degrees, premium flexible material, and water- and stain-resistant properties. This option acts as a corner guard, caulk strip, and transition strip in one. Best for corners in high-traffic areas like kitchens, bathrooms, and living rooms with potential moisture exposure.
Best for: spaces requiring adjustable corner protection that can adapt to various wall angles and edge transitions. Choose this if you want a single product that handles 90-degree turns and wider corners with minimal trimming.
Caution: Adhesive backing performance can vary by surface; ensure the wall is clean and smooth for optimum adhesion.
Outwater 1921-Bk Black 1” X 2” Edge Moulding

Features include 2″ x 1″ uneven legs and a 90-degree angle. Best for protecting broader edge surfaces on larger furniture panels or cabinetry where a stronger, wider trim is beneficial. The slightly uneven leg design can help absorb impacts on flat-topped corners.
Best for: larger edge protection on furniture pieces or cabinets requiring more surface coverage. Choose this if you need a sturdier profile than a 1×1 trim.
Caution: Slightly thicker profile may require wider gaps at the joint; verify fit before alignment with existing trim.
Kikerike 2.4 Inch X 10 Feet Corner Protector

Features highlight self-adhesive backing for tool-free installation, adjustable width and length, and durable PVC material with water resistance and easy cleaning. Also noted for universal compatibility with drywall, wood, metal, or tile surfaces, and multi-purpose use as edge guards for tables, countertops, or stair edges.
Best for: long runs and situations where a quick, tool-free install is preferred. Choose this if you want a flexible, paint-ready edge guard that can be cut to fit irregular corners.
Caution: Creasing along the center prior to installation aids bending but may require careful handling to avoid creasing after application.
Outwater 1940-Bk Black 1.5 X 1.5 Edge Moulding

Features include 1.5″ x 1.5″ even legs and a thick 3/64″ profile with an 87 to 90 degree angle. Best for larger edge corners on display cases, furniture with substantial edge exposure, and installations needing a robust, visible trim.
Best for: high-visibility corners or thicker edge profiles where a strong, substantial trim is desired. Choose this if you must cover larger or more prominent corner joints.
Caution: The larger footprint may require more precise cutting and alignment; plan measuring before installation.
Buying Guide
What to consider when selecting 90 degree plastic trim:
- Edge size and profile: Match the trim width to the edge it protects; smaller profiles suit fine furniture, larger profiles cover broader corners.
- Angle tolerance: Most options support near 90 degrees; verify whether your project requires exactly 90 degrees or a flexible transition.
- Mounting method: Adhesive-backed trims are quick to install, but surface condition matters. Screwed or clipped profiles offer more permanence for high-traffic areas.
- Material durability: Styrene and PVC trims resist impact and moisture differently; consider room environment (kitchens, bathrooms, workshops) when choosing.
- Flexibility vs rigidity: Flexible corner guards adapt to curved or irregular corners, while rigid mouldings provide a sharp, clean line on flat edges.
- Finish and color: Black and white finishes blend with most decors; consider contrast versus camouflage with furniture or walls.
- Installation surface: Drywall, wood, tile, or metal surfaces affect adhesion and longevity; prepare surfaces for best results.
