Containment Sump Accessorie% <br />Containment collars <br />Each Xerxes containment collar is factory -banded to a <br />tank to provide a secure fit for the containment sump <br />installation. Both single-wall and double-wall Xerxes con- <br />tainment collars come in 42" and 48" diameters. Xerxes <br />containment collars are manufactured for both round and <br />flat -sided containment sumps. <br />Single -Wall, Round Containment Collar <br />Cover options <br />Xerxes containment sumps come in a variety of cover <br />designs and sizes. Each sump model is available with a <br />watertight cover, a friction -fit cover or an open top. The <br />covers fit both Xerxes round and flat -sided sumps. In <br />many applications, the Xerxes watertight cover offers <br />customers significant advantages over other manufactur- <br />ers' cover designs. The Xerxes containment -sump cover <br />has been widely used for nearly two decades with an <br />excellent track record in a variety of applications, includ- <br />ing in high water -table conditions and in areas with <br />heavy rainwater. Both the 30" -diameter fiberglass water- <br />tight cover and the 26" -diameter polyethylene watertight <br />cover have an easy-to-use, lever -locking ring that is <br />designed for positive locking (similar to a barrel lock). <br />The lever lock easily compresses the closed -cell gasket to <br />form a watertight seal. <br />Collar channel for hold-down strap <br />Collar channels for hold-down straps are an innovative <br />solution for strapping when short tanks or tanks with a <br />number of collars limit the available ribs for strap loca- <br />tions. This channel allows a strap to be stretched across the <br />rib through the channel while maintaining the watertight <br />integrity of a sealed collar. The channels are available for <br />both single-wall and double-wall collars. <br />Adhesive <br />Xerxes provides Bosdk-0 adhesive <br />with all single-wall sumps to allow <br />for field installation and sealing of <br />the sump to the collar. Bostik has a <br />long, proven track record in this <br />application and provides for an <br />easy, user-friendly application. <br />Bostik does not require the two- <br />part mixing that is common in <br />many adhesives. Another advan- <br />tage is that Bostikdoes nor require <br />hazardous material handling and <br />shipping. <br />26" Friction -Fit <br />Cover <br />30" Watertight <br />Cover <br />
