Closing Plugs - Seal and Protect the Threaded Holes in Horseshoes

We offer various horseshoe models with threaded holes for stud application. These models can be devided in two categories - those with threaded holes fixated inside the synthethic material and those where the stud holes are integrated inside the metal core. All models with stud holes securely anchored in the metal core are suitable for regular stud changes. The models in which the threaded insert is fixed in plastic are not suitable for regular stud changes.

However, for all threaded horseshoes, it is essential to seal the stud holes with a placeholder (a so-called closure plug) during times without studs. This is done to protect the threaded hole from excessive dirt. This helps to maintain the stability of the shoe in the area of the threaded inserts to prevent unwanted pressure on the hoof.

Your Selection of Closing Plugs at a Glance

For those familiar with our company history, it is known that Hubert Frank started with FRANK'S studs right from the beginning. Our closure plugs also date back to that time; therefore, they are suitable for use in conventional steel horseshoes as well. The table provides details on the compatible closure plugs for steel shoes and composite shoes, in the latter case specifying the type of threaded inserts, whether fixated in synthetic material or a metal core.

The primary advantage of plastic closing plugs lies in their easy handling. However, the use of the metal threaded plug is quickly accomplished with a bit of craftsmanship. Take a moment to watch our video for a demonstration.
