When choosing a thimble for your application, it’s important to consider what type of environment the thimble will be used in. E-Rigging offers thimbles that are made from Zinc Plated Steel, Hot Dipped Galvanized Steel, and Type 316 Stainless Steel.
Starting with the most corrosion resistant, stainless steel thimbles are best suited for being used in outdoor applications and are highly resistant to rust. Stainless Steel thimbles are also ideal for being used in or near saltwater environments where corrosion frequently occurs, and are the best choice when using stainless steel cable or chain.
Our heavy duty, hot dipped galvanized thimbles come in at a lower cost than stainless steel, and are also suited for outdoor environments. While galvanized components are also ideal for outdoor use, galvanized components can exhibit signs of surface rust if the galvanized coating is worn off on the load bearing or contact areas of the component, this type of surface rust is normally worn off when loaded or used, and shouldn’t affect the component’s performance.
Our light duty zinc plated thimbles can also be used outdoors, but it’s important to be aware that a zinc coating is thinner than a hot dipped galvanized coating, so the thimble may exhibit signs of rust earlier than a hot dipped galvanized thimble, this is especially true in environments where the thimble will be exposed to rain or snow, or in salt air or salt water environments.
The size of vinyl coated cable can be confusing because some manufactures measure different vinyl coated cable diameters. E-Rigging lists vinyl coated cable by the cable diameter, so the vinyl coating diameter adds a little thickness. The finished or final cable diameter is listed on the product pages of E-Rigging’s website. It typically coincides with the next size larger thimble. For example, if you are using 3/16" vinyl coated cable that is coated to 1/4" diameter, you’d want to use a 1/4" thimble.
When using stripped vinyl coated cable, you are going to want to size it just like uncoated cable. So, if you are using 3/16" x 1/4" vinyl coated cable, use a 3/16" thimble.
