Value and versatility are built into telescopic spreaders by TANDEMLOC. The telescoping bar offers a wide range of minimum and maximum lengths in convenient increments of only a few inches.  We have a countless selection of telescopic spreaders, so contact us if you do not see one here that fits the need.  We probably have one that will do the job and if we don't, they are a snap for us to customize.  As for slings, we can supply them too.  Some designs show a sling as a separate item number and some incorporate a sling as part of the spreader and others don't offer a sling.  Please check the drawings carefully or just ask--we can provide the sling if needed.  As for the spreader bar end design, yes these can be made with clevis ends to eliminate shackles.  Also, the bars can be designed for low sling angles. Everything is proof tested without extra charge! Lift with confidence!
