And with a flush bottom sill, the CG3S is idea for high traffic environments. Because these doors are engineered with mechanical seals, no air pressure or power is needed and maintenance requirements are minimal. Every CG3S is custom built to your exacting dimensions. For existing openings, the frame is mounted to the face of the building with expansion anchors; a trench is cut into the existing concrete floor and the sill is cast in place. For new construction, the track and frame are poured in place. #### COMPLETE FLOOD PROTECTION IN UNDER ONE MINUTE When floodwaters threaten, simply open the hinged sill and jamb cover plates and roll the sliding flood barrier into place.  Simply turn the handles and the opening is secured. #### APPLICATIONS — THE CG3S SLIDING FLOOD BARRIER AT WORK The CG3S sliding flood barrier is ideal for environments where heavy traffic requires a flush floor sill but fast and easy deployment is desired with minimal aesthetic impact.  Because the barrier is hidden from view when not in use, remote storage and deployment logistics are eliminated. ![CG3S sliding flood barrier diagram](https://www.presray.com/hs-fs/file-20139564-png/images/cg3s-diagram1.png) # CG3S Product Specifications | #### Size | Custom built to match opening size | | --- | --- | | #### Panel | 6061-T6 Aluminum plate | | #### Frame & Track | Low carbon steel (Stainless Steel & 6061-T6 Aluminum plate optional) | | #### Seals | Presray type 25 durometer, fully-molded neoprene (other materials are available for special environments) | | #### Hardware | Shrouds: 6061-T6 Aluminum (other materials available) Compression Handles: Presray type handles with stainless steel rollers  | | #### Finish | Panel: Bright Aluminum Plate Conversion Frame: Primed with rust inhibitive, lead free, red primer  | # Image Gallery - ![](https://www.presray.com/hs-fs/file-28954470-jpg/gallery/album/11631/cg3s-skeleton-closed.jpg) - ![](https://www.presray.com/hs-fs/file-28954688-jpg/gallery/album/11631/cg3s_01-lrg.jpg) - ![](https://www.presray.com/hs-fs/file-28955211-jpg/gallery/album/11631/cg3s_st.joe3_lg.jpg) - ![](https://www.presray.com/hs-fs/file-28954919-jpg/gallery/album/11631/cg3s_02-lrg.jpg) - ![](https://www.presray.com/hs-fs/file-28955793-jpg/gallery/album/11631/dsc00089.jpg) - ![CG3S Sliding Floodgate in open position.](https://www.presray.com/hs-fs/file-28955602-jpg/gallery/album/11631/dsc00088.jpg "CG3S Sliding Floodgate in open position.")
