1) Construction: Conventional four parts – fork, cantle and two bars. A rigid fork and cantle assembled together with flexible bars. The rigid fork and cantle maintain proper bar rafter angle and spread while the flexible bars allow the tree to bend along with your horse’s spine.
2) Materials: Forks and cantles – most are identical to EFC, fiberglass-covered wood/plywood. We offer a limited number of styles molded of a structural elastomer reinforced with a fiberglass mesh. Bars – EFF bars are molded of a material similar to a rubber-like work boot sole. This state-of-the-art elastomer owes its flexibility to the molecular structure; it does not come from an added softening agent that will eventually evaporate leading to drying out and cracking.
3) Assembly: EFF bars are molded with a well defined socket for both the fork and cantle, eliminating incorrectly measured trees. The elastomer has memory insuring distortion-free parts that always set up square and level.
4) Fasteners: All EFF fork-to-bar and cantle-to-bar joints are fastened using five #10 screws, four 3 1/8” and one 1 ¾”. We are unaware of a single example of the screw heads pulling through the flexible elastomer.
5) Coverings: All wood forks and cantles are covered with 6 oz. fiberglass cloth just as EFC trees. All molded parts – forks, cantles or bars – have sufficient strength so that no additional covering is necessary.
6) Fits: Our goal is to have our EFF line feature all eight fits represented by FTBS. We don’t have them all at this time, but the flexibility allows independent modification of the bar rafter angle front and rear. This allows us to more properly fit a wide spectrum of back types even as we complete tool-up on our standard fits.
7) Styles: Every style fork and cantle available in our EFC line is likewise available in EFF.
