Compatible with SafePort Rugged tablet cases THD135GLZ and THD136GLZ, the Hand Strap fits onto the case's integrated sliding stand. Just press the clips underneath to remove the hand strap. Once you're ready to attach it, snap it into place on both sides of the handle. When it is snapped in place, the soft neoprene strap facilitates one-handed use of the tablet whether you're at a job site, in the field, or just want to multi-task.
