Extra Float Stick kit is an add-on to the Standard Kit when additional sticks are preferred or when needed for irregular, odd shaped shower layouts. EFS-101.2 is also used in place of the Standard Kit in linear drain type showers that will not use a Center Ring. All float sticks can be used with any waterproofing method. Extended sticks are available to continue the slope up to 72” from the drain. Each stick measures 1 in. to 1 3/4 in. tapered x 36 in. length. Sold 4 per package. Instructions included.
