Weighing under 11 grams, our 3" long (75 mm) extenders, are made lighter & straighter and feature an improved insertion bit 3/4" long (35 mm) which requires very little adjustment for a tight and secure fit with steel shafts. Note: Extending a club more than 2 inches may compromise shaft integrity and increase the risk of breakage Aluminium 11 Grams 1.5" Insertion - 4.5" Overall
