ShapeShift® pitch pans consist of straight and outside corner sections that snap together to create an endless number of pitch pan sizes to seal around roof projections. The radius corner pieces measure approximately 2" x 2". The straight sections measure approximately 3" long. The high-strength polymer pieces have a 2-1/2" base flange with a 1-3/4" high side. The pieces snap together with interlocking joints. The smallest pitch pan possible is 4" x 4" (4 corner pieces). The maximum size is unlimited. ShapeShift® pitch pans are approved for installation on Mule-Hide warranted projects when installed on vertical surfaces if filled with JTS 1 sealant instead of MP Liquid Sealant.
