Each STRONGBOX comes with three layers of foam protection in either 350 lb. or 500 lb. corrugated cardboard. STRONGBOXES are also available with Puncture-Guard hard plastic liners ensuring extra safety for expensive art work.

Framed art work is safely encased in three layers of protection. One layer is sandwiched between two layers of convoluted (egg carton) foam. Customize the middle foam layer by removing perforated squares to form an opening that snugly encases the art work. Multiple layer proved superior shock absorption.

STRONGBOXES provide an inexpensive and reuseable shipping carton suitable for land and air transit with excellent damage survival qualities to withstand UPS, U.S. Mail and air courier handling.
