If you have multiple lifts coming up requiring spreader bar lengths in a similar range, then the Alltec adjustable telescopic spreader bars are your best fit. No need to change pipe insert in between lifts, no need to change out a bolted insert. Just lower the spreader on its legs, adjust the length and secure the lock pins again prior to lifting. Alltec carries adjustable telescopic spreader bars from 8ft-12ft to 35ft-55ft with WLL’s varying from 50T to 250T.
