{"product_id":"closed-cell-backer-rod","title":"Soft Type Backer Rod, 1 Carton — ASTM C1330 Type B","description":"\u003cp\u003eSoft-type polyethylene foam backer rod for controlling sealant depth in glazing and building joints. Bi-cellular and highly compressible, it seats into irregular and variable-width joints without gassing or bubbling the sealant. Sealants will not adhere to it, so no separate bond breaker is required.\u003c\/p\u003e\u003cp\u003eIt holds your sealant at the correct depth so the bead forms the proper hourglass profile and moves the way it was designed to, and it cuts the volume of sealant the joint consumes. Produced without CFCs or HCFCs.\u003c\/p\u003e\u003ch3\u003eWhich diameter for your joint\u003c\/h3\u003e\u003cp\u003eThe joint is the gap between the two pieces you are sealing — pane to frame, panel to panel, slab to slab. Measure that gap and pick the rod one size larger, so it squeezes in and stays put: roughly 25% larger than the gap, installed at 25% to 50% compression. A rod that drops in loose does nothing.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eRod diameter\u003c\/th\u003e\n\u003cth\u003eGap it is made for\u003c\/th\u003e\n\u003cth\u003eFull carton\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e5\/8 in (16 mm)\u003c\/td\u003e\n\u003ctd\u003e3\/8 to 1\/2 in wide\u003c\/td\u003e\n\u003ctd\u003e1,550 ft \/ 472 m, two spools\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e7\/8 in (22 mm)\u003c\/td\u003e\n\u003ctd\u003e1\/2 to 3\/4 in wide\u003c\/td\u003e\n\u003ctd\u003e850 ft, one spool\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1 1\/8 in (29 mm)\u003c\/td\u003e\n\u003ctd\u003e3\/4 to 7\/8 in wide\u003c\/td\u003e\n\u003ctd\u003e500 ft \/ 152 m, one spool\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003eSold by the full carton only, minimum order one carton.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandard\u003c\/td\u003e\n\u003ctd\u003eMeets or exceeds ASTM C1330 Type B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eRound extruded bi-cellular polyethylene, black, water-resistant outer skin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDensity\u003c\/td\u003e\n\u003ctd\u003e1.6 to 2.0 lb\/ft3, ASTM D1622\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutgassing\u003c\/td\u003e\n\u003ctd\u003e0 bubbles, ASTM C1253\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompression recovery\u003c\/td\u003e\n\u003ctd\u003eOver 97%, ASTM D5249\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater absorption\u003c\/td\u003e\n\u003ctd\u003eUnder 0.03 g\/cc, ASTM C1016 Proc.
