608 Pivot Whiffletree Load Equalizer Bar
A 134 mm whiffletree (balance beam) that pivots on a press-fit 608 bearing (22.05 mm pocket, 16 mm through-bore for an 8 mm bolt or rod). It splits one pull into two equal or ratioed pulls for twin cables or tendons, cart or sled traces, or two-point lifts. Three pairs of M4 clearance holes (4.5 mm) sit at 30, 45 and 60 mm from the pivot. Using matched holes gives a 1:1 split, and mixing them gives 1.5:1, 2:1 and other ratios.
