Rolled-rim grommets are exclusively used with spur washers.
The spurs lock into the rim of the grommet as they grasp the material, providing the strongest possible setting.
They are available in brass, with plain finish or special finishes such as nickel and black zinc. Most sizes are also available in 304 stainless steel. Paskal stock and recommend using 304 stainless steel.
Rolled-rim grommets and spur washers are used in awnings, bags, large size banners, car mats, curtains, fall protection harnesses, flags, netting, pool covers, sails, tarpaulins, tents, etc. They are the most reliable way to reinforce holes in different materials for long-lasting tear prevention.
