The Dayton Superior F44 Thin Slab Ferrule Insert is a specially designed insert for use where the depth of embedment is extremely limited and where there is a requirement for limited capacity in both tension and shear. Depending on region, the F44 will be furnished with either two struts welded to the bottom of the ferrule or one strut looped around the ferrule (see sketch). Minimum spacing between inserts is twice the minimum corner distance.
