Pull-ring plugs feature easy removal with a tapered style and built in lift rings. This also makes installation simple and reduces the chance of product damage. The pull rings are designed to lay flat when not in use to make packaging more efficient.
Sheet metal plugs are used for a range of applications such as appliances, rust proofing, automobiles, and hot water tanks. They can provide a reliable, secure plug in thin materials.
