3M 7000029678 Bumpon SJ5309 Clear Rubber Bumper

Product Description

The 3M 7000029678 is a self-adhesive rubber bumper from the Bumpon Protective Products line, sold under product designation SJ5309. It features a cylindrical body with a concave top profile, measuring 0.88 inches wide by 0.40 inches high. The pressure-sensitive adhesive backing bonds to most clean, dry surfaces without fasteners or tools. These bumpers serve as protective feet, stops, and spacers across a wide range of assemblies and enclosures. The clear finish keeps the part low-profile and unobtrusive on finished surfaces. Each unit ships individually and is suited for high-volume procurement in industrial and light manufacturing environments.

Bumpon SJ5309 bumpers are used wherever a surface needs protection from impact, vibration, or unwanted movement. Common applications include electronic enclosures, equipment panels, cabinetry, and fixtures that require a durable, non-marking contact point. The concave top profile is specifically suited for custom applications where a standard flat or dome top would not provide the required fit or contact geometry.

Key Features

• Self-adhesive backing for tool-free installation on clean, dry surfaces
• Cylindrical shape with concave top for custom fit applications
• Clear finish for low-visibility placement on finished surfaces
• Functions as a foot, stop, or spacer depending on application
• Rubber construction provides cushioning and vibration dampening

Compatibility

Designed for general-purpose use as a protective bumper, foot, stop, or spacer on equipment panels, enclosures, cabinetry, and similar surfaces where a self-adhesive rubber standoff is required.

Installation Notes

Clean and dry the mounting surface thoroughly before applying the adhesive backing to ensure proper bond strength. Peel the liner, position the bumper, and apply firm pressure for several seconds. No special tools or trade licensing are required for installation. Allow adequate dwell time before the assembly is subjected to load or movement.
