All of our cube-type workholding can be supplied with a broad range of accessories. These include, but are not limited to, the following:

LIFTING EYES

Both fixed and swivel style lifting eyes to facilitate the safe handling of your tombstone-based workholding and fixturing. All tombstone-based workholding includes tapped holes in the top face (appropriate tap size for assumed weight). The position and size of lifting holes can be altered to specification.
