Master Magnetics Inc. RB20CBX Round Base Magnet 5 Lb

Product Description

The MASTER MAGNETICS INC. RB20CBX is a ceramic round base magnet rated for 5 pounds of pull force. It features a low-profile disc design with a center attachment hole, allowing a hook, knob, or fastener to be threaded through for secure mounting. The nickel or nickel/chrome plating provides corrosion resistance and durability in light industrial and trade environments. Magnetic force is concentrated on one face, giving a strong, flat hold against steel surfaces. Technicians and tradespeople use this style of magnet to hold inspection equipment, dial indicator gauges, lamps, signs, and antennas in position during service or installation work.

The RB20CBX suits applications where a compact, low-profile magnetic base is needed on ferrous surfaces. At 1.9 inches in diameter and 0.25 inches in height, it fits into tight spaces and mounts flush. Common uses include temporarily securing indicators or gauges during HVAC, electrical, or plumbing inspections, mounting signage or identification tags, and holding small tools or accessories in position on metal panels or enclosures.

Key Features

• 5 lb pull force for reliable temporary or semi-permanent holding on ferrous surfaces
• Center attachment hole accepts hooks, knobs, or threaded fasteners
• Magnetic on one side only for controlled, directional hold
• Nickel or nickel/chrome plating for durability and corrosion resistance
• Low-profile design at 0.25 inches height fits confined spaces
• Ceramic magnet construction for stable performance across typical service temperature ranges

Compatibility

Designed as a general-purpose round base magnet for use on flat or curved ferrous steel surfaces in trade and light industrial applications.

Installation Notes

No tools are required to attach the magnet to a steel surface. When threading a hook or fastener through the center hole, ensure the hardware matches the hole diameter to avoid cracking the ceramic disc. Do not apply excessive lateral force, as ceramic magnets are brittle and can fracture if dropped or struck. Keep away from sensitive electronic components, magnetic media, and pacemakers during handling.
