Flat Hem with Grommets: This standard hem has double-folded edges, #4 rolled-rim brass grommets, and spur washers. Each grommet measures:
• 0.645-inch inside diameter and 1.312-inch outside diameter
• 1.01-inch spur washer with interlocking teeth
Made in America, these weather-resistant brass parts work well outdoors. The breathable cotton canvas material withstands harsh conditions while remaining secure.
Grommets with Reinforced Patches: Recommended for higher tension settings like camping shelters, this version adds three extra layers of canvas around each grommet for added strength. It uses the same #4 rolled-rim brass grommets and spur washers as the flat hem. Made in America, it provides extra stability under stress.
D-rings with Reinforced Patches: Designed for tasks like securing truck bed loads, this style includes reinforced canvas patches and steel-plated zinc D-rings. Each 1-1/8-inch D-ring is sewn onto seat belt webbing for a stronger hold. Four-layer reinforced patches add further durability. Made in America, they perform well in tough conditions.
All Humphrys Products Are Sold at Finish Size, Not Cut Size.
Finish Size means the product you receive will match the advertised dimensions. Hemming involves folding and stitching the edges for added strength, which reduces material's size. When manufactured at 'Finish Size', products are cut larger at the beginning, so that they end up matching the advertised size after hemming.
Historically, tarps were sold at 'Cut Size', where the tarp only met the advertised measurements before hemming, and the actual resulting product was smaller. Some manufacturers continue to use this standard. When buying textiles, make sure you are getting a product that is Finish Size to avoid receiving a product that is smaller than expected.
