For the more-common Kennedy "Hexacut" Model 60 hacksaw the flat belt is normally 1" (25 mm) wide and 21.8" long (554 mm) - however, because the size may have changed over the years, it would be safer to measure your machine to get an exact figure. As the belts are custom made, if you order the wrong length a refund is not possible. An accurate measurement can be taken around the pulleys with a fabric tape measure or a strip of paper stretched round, overlapped, marked and then carefully measured. Please put the length details in the order comments' box. You might also want to turn the machine upside down and check the position of the adjustment bolts to see if they have allowed the unit to be moved back to tension an older belt. If so, slacken the bolts and push the unit forward to get the minimum belt length; this will will allow the maximum adjustment for stretch. The rarer and larger Model 90 "Hexacut" was fitted with a belt 1.25" (32 mm") wide and (32.5" 825.5 mm) long - though again it's best to measure yours carefully before ordering. Belts can be made to an exact length and are £28.80 including post, packing and VAT. The belts are endless, as per the original type, and made from a high-quality Swiss-made material designed for machine-tool drives.
