The PD Series utilizes a patented hinge that will accommodate 2" of vertical movement or uneven slabs. The PD Series requires minimal concrete preparation when compared to conventional parking deck models, resulting in reduced installation time and costs. This product is available with EPDM membrane that will create a watertight seal, preventing water or chemicals from dripping to floors below. The PD Series is recommended for walkways, parking decks, elevated roadways, boat ramps, and deplaning ramps. The PD Series can also be utilized in threshold applications.   D:\Sites\LocalUser\nystrom\content\0006.htm      © 2005 Nystrom
