The 3M™ DBI-SALA® Advanced 4-in-1 Davit Guard System 8530352 is designed for confined space entry, retrieval, and worker protection. Combining a davit hoist system with an integrated guardrail structure, it provides both lifting capability and passive fall protection around the opening. Built from lightweight, corrosion-resistant aluminum, the system assembles quickly without tools and features a folding base to simplify transport and storage while maintaining durability in demanding industrial environments.

Key Features

4-in-1 davit guard system: Combines hoisting capability with a passive guardrail protection system.
Integrated 5,000 lb (22 kN) anchorage point: Provides a secure tie-off location for fall protection equipment.
Fall arrest rated in all davit offset mast positions: Supports reliable fall protection during entry and retrieval operations.
Built-in pulley system: Facilitates lifeline routing and smooth operation.
Quick-mount winch/SRL bracket: Enables efficient installation of compatible retrieval devices.
Secondary fall arrest anchorage point: Adds additional fall protection capability.
Telescoping upper davit mast: Allows height adjustment to adapt to jobsite requirements.
Guardrail with hinged gate: Helps protect workers and bystanders around the confined space opening.
Tool-free assembly: System can be set up and dismantled quickly without tools.
Adjustable leveling system: Unique foot level and height adjustments support proper positioning.
Folding lightweight base: Reduces transport and storage space requirements.
