**Exact dimensions.** True size, with no tolerance added.

## Notes

- PowerGrip XL: 1/5 in (5.080 mm) pitch, trapezoidal teeth. The designation is the pitch length in tenths of an inch (100-XL is 10.0 in = 254.00 mm = 50 teeth), so teeth = designation / 2 and length = teeth x 5.08; every row printed in Gates' catalog page 52 agrees with that (checked in the generator).
- 120 lengths from 46-XL (116.84 mm, 23 teeth) to 770-XL (1955.80 mm, 385 teeth). Widths on the page: 6.4, 7.9 and 9.5 mm.
- The page marks some lengths as stocked in bold; the extraction lost that, so no stock claim. L, H, XH and XXH belts are on the same Gates page but their full lists were not read here.
