Dunn & Watson Heavy Duty Cast Door Hold Back – Secure, Strong, and Built to Last
Dunn & Watson’s heavy duty cast door hold backs are engineered for demanding environments where durability and reliability are non-negotiable. Made from cast steel, these robust catches are perfect for securing large doors on trucks, trailers, buses, and heavy service vehicles. Designed to keep doors firmly in place, they’re ideal for situations that involve slamming closures or rough usage.
The system includes both male and female components, designed to provide a strong, spring-assisted hold without the need for a keyed lock. When engaged, the female end flexes to release the male section, allowing the door to open smoothly without sacrificing security.
