    The whole idea of these, I think, is to keep water and subsequent rust out of the square tubing. They do that and their relatively low price makes them a worthwhile investment. You might want install them with some adhesive.

    I bought these to use on an exercise bench. I pulled off the rubber feet that typically keep the bench secured on the floor in order to drill/install some locking caster wheels. I needed to be able to move the bench around easily in my garage gym. Pulling those rubber feed off exposed the ends of the square tubing. These square end caps were the finishing touch to the exposed square tubing. Works as advertised.

The exterior ribs are High-Grade to provide a sure grip inside a tube without the unsightly plastic shavings found on many straight wall glide installations. Not subject to rust or corrosion.
