90° Railing Corner Caps for Clean, Professional Transitions

Smooth, Gap-Free 90° Turns

90-degree railing corner caps create crisp, finished corners on vinyl-covered rails. They hide raw edges, prevent snag points, and deliver a uniform look across the entire run.

Durable, All-Weather Fit

Made for outdoor use, these weather-resistant caps stand up to sun, rain, and temperature swings. They hold their shape and color season after season.

Compatible with 2×4 and 2×6 Systems

Designed to pair with our vinyl handrail covers, the caps seat securely at inside or outside 90° turns—ideal for decks, porches, and stair landings.
