Master Magnetics rb45c Round Base Pot Magnet 16 Lbs Pull

Product Description

The MASTER MAGNETICS rb45c is a ceramic round base pot magnet designed for secure single-sided holding in industrial, commercial, and household applications. It measures 1.425 inches in outer diameter, 0.375 inches in inner diameter, and 0.283 inches thick, with a 0.190-inch center hole. The center hole accepts a hook, stud, or knob, allowing the magnet to be mounted or suspended from a variety of surfaces and fixtures. With a rated pulling force of 16 pounds, it provides reliable holding strength in a compact, low-profile form factor. The nickel and chrome plating adds corrosion resistance and surface durability for extended service life.

This pot magnet is suited for light-duty mounting and positioning tasks across residential, commercial, and industrial settings. Typical applications include holding inspection equipment, dial indicator gauges, work lamps, antennas, and signage to ferrous metal surfaces. Sporting, shop, and facilities maintenance professionals use this style of magnet for temporary or semi-permanent fixture work where drilling or permanent fasteners are not practical. The single-sided magnetic face concentrates holding force against the target surface while the non-magnetic back and plated shell keep the assembly clean and handleable.

Key Features

• 16-pound rated pulling force in a 1.425-inch OD footprint
• Center hole (0.190 inches) accepts hooks, knobs, or studs for flexible mounting
• Ceramic magnet construction provides stable holding force across typical ambient temperatures
• Nickel and chrome plated steel shell for corrosion resistance and durability
• Single-sided magnetic face concentrates flux for maximum surface-contact holding
• Low-profile design at 0.283 inches thick fits tight clearance installations

Compatibility

Designed as a general-purpose round base pot magnet suitable for use on flat or gently curved ferrous metal surfaces in industrial, commercial, and residential applications.

Installation Notes

Attachment hardware such as hooks or threaded studs should be matched to the 0.190-inch center hole diameter before installation. Ensure the target mounting surface is clean, dry, and free of paint or debris that would reduce effective holding force. Pulling force ratings are measured against flat, clean mild steel and will be lower on painted, uneven, or oxidized surfaces. No tools or electrical power are required for standard positioning use, but fastener installation into the center hole should follow the hardware manufacturer torque guidance.
