The Mak kee Sling Calculator is a free app that lets you design and configure grade 8 and grade 10 chain slings by taking you through a number of easy steps. Once completed, the sling specification can be viewed along with a 3D image of exactly how the sling will look.

A part code for the sling is generated and by hitting ‘request quote’ you can have a quote emailed to yourself instantly. This key feature is great for when working on site.
