Blum 39C355B 1-1/4 in Overlay Soft Close Cabinet Hinge - Compact Quiet

Our review of the Blum 39C355B 1-1/4 in overlay soft close hinge finds it best suited to homeowners and cabinetmakers who need a compact, dependable hinge that keeps doors closing silently. The single biggest reason to buy is the integrated soft-close Blumotion mechanism built directly into the hinge cup, which delivers smooth, quiet closing without adding bulk. The hinge is small, economical, and designed to fit 1-1/4 in overlay doors while still offering three-dimensional adjustment so doors align precisely.

Key Features

• Integrated Blumotion: The soft-close damper is built into the hinge cup, providing silent, controlled closing regardless of door weight or closing speed.
• Deactivation switch: A one-hinge deactivation option lets installers disable the blumotion for very small or light doors to avoid unwanted resistance.
• Overload safety: The hinge has an overload safety feature that reduces stress on the mechanism and prolongs life under heavier use.
• Wraparound design: The one-piece wraparound hinge-to-frame mount provides a sturdy connection and requires a truss head installation screw.
• Compact profile: Designed as Blum's smallest hinge with a 110 degree opening angle, it saves space while maintaining soft-close performance.
• Screw-on door attachment: The screw-on hinge-to-door fitting simplifies installation on 1-1/4 in overlay doors for a reliable hold.

Who It's For

The Blum 39C355B is ideal for DIYers, cabinetmakers, and remodelers fitting inset or overlay cabinets where a small hinge profile and quiet operation are priorities. It suits kitchens, bathrooms, and utility cabinets where the soft-close action improves perceived quality and reduces slamming noise.

Those who should look elsewhere include buyers who require specialty finishes or integrated mounting plates not provided here, and anyone expecting installation screws to be included in the pack should plan to source compatible truss head screws separately.
