Sugatsune LB-S350 Lid Stay Damper 154 Lb Stainless Steel

Product Description

The SUGATSUNE LB-S350 is a lid stay damper designed to control the opening and raising of lids, hatches, and access panels in industrial, commercial, and architectural applications. It provides controlled motion and holds lids in the open position under load, reducing stress on hinges and mounting surfaces. Built from 304 stainless steel with a satin finish, it is suited for environments where corrosion resistance and clean aesthetics are required. The LB-S350 is non-handed, meaning it installs on either side of a lid assembly without needing a mirrored part. Overall length is 400 millimeters (approximately 15.75 inches) and width is 45 millimeters (approximately 1.77 inches or 1-25/32 inches).

This lid stay damper is used in applications where heavy lids, covers, or access doors require controlled support during opening and secure holding in the raised position. Typical installations include industrial enclosures, marine cabinetry, architectural millwork, and heavy-duty equipment access panels. The non-handed design simplifies procurement and reduces inventory for projects requiring multiple units. Its stainless steel construction makes it appropriate for food service, marine, pharmaceutical, and other demanding environments where carbon steel hardware is not acceptable.

Key Features

• 304 stainless steel construction for corrosion resistance in demanding environments
• Satin finish suitable for exposed architectural and commercial installations
• Non-handed design installs on either side of a lid assembly without a mirrored counterpart
• 400 millimeter (approximately 15.75 inch) overall length for coverage on larger lid spans
• Supports and controls heavy lid assemblies with a rated load capacity up to 293 pounds

Compatibility

Designed as a direct-mount lid stay damper for heavy lids, hatches, access panels, and enclosure covers in commercial and industrial equipment where a controlled-open mechanism is required.

Installation Notes

Installation is typically performed by millworkers, marine fabricators, or industrial equipment technicians using standard hand tools. Mounting surfaces must be structurally sound and fastener holes should be properly sized to handle the rated load. Verify that the lid weight and geometry fall within the rated capacity before installation. Follow all applicable structural fastening guidelines for the mounting substrate material.
