    Light Duty Unthreaded Spacers

    Image of Product. Front orientation. Spacers. Light Duty Unthreaded Spacers.
    An economical choice for low-load applications. Made from low-carbon steel, these spacers have a lower tensile strength than standard steel spacers. Unlike standard versions that are often cut from seamless tubing, these are formed by molding flat-coil steel into shape. This process creates a thinner spacer with a visible seam that’s best for light duty tasks.
    Zinc-Plated Low-Carbon Steel—A common choice for areas with occasional exposure to moisture.
    Galvanized Low-Carbon Steel—Resist moisture better than zinc plating but may degrade when exposed to salt water and chemicals.

    Adhesive-Back Bumpers

    Image of Product. Front orientation. Bumpers. Adhesive-Back Bumpers, Style 3.

    Style 3

    Stick these bumpers onto glass and other surfaces that are too fragile or thin for fasteners. Their adhesive sticks to your surface without scratching or discoloring it. From spacers to sound dampeners, they have a wide range of uses. They’re comparable to Bumpon bumpers.

    Abrasion-Resistant Polyurethane Rubber—Choose these bumpers for a balance of toughness and flexibility. Rough surfaces and repeated knocks won't wear them out, so you can use them as feet for small equipment and stops for cabinet doors and drawers.
    Hardness Rating—The harder the bumper, the better it withstands impact and abrasion over time. The softer the bumper, the more cushioning it provides for objects made of glass, soft metal, and other fragile materials. Bumpers with a medium rating offer a balance of impact resistance and cushioning.
