【HEAVY-DUTY CONSTRUCTION】- Our windshield truck rack is made of heavy-gauge 45# steel material, with strong durability and sturdiness. Each mast is built for long-lasting reliability, with black powder coating. 【HOLD UP TO 9 WINDSHIELDS】- This windshield rack for truck comes with ten masts per side, holding up to 9 windshields at one time. 【RELIABILITY & STABILITY】- Due to the special-designed lock system, the windshields can be locked in place to prevent the windshields from slipping out. The masts are covered with foam padding, featuring bottom cushion made of PVC pad, to minimize the damage done to the windshields. 【ELASTIC BAND AVAILABLE】- An additional elastic band is available for free, with a length of 78.7-inch (2.0 m). It can play a stable and fixed role in the windshields' transportation and reduce the breakage due to the bumpy road. 【MULTIPURPOSE GLASS RACK】- This glass rack carrier is a perfect tool for auto-glass shop owners who handle a large volume of windshields. It is suitable for mounting on the truck and van bed.
