{"product_id":"jl-industries-diamond-series-galvanneal-roof-hatch","title":"JL Industries Diamond Series Galvanneal Roof Hatch","description":"\u003cp\u003eThe JL Industries Diamond Series is an insulated galvanneal roof hatch for permanent roof access, made in the USA. The curb and cover both carry 1 in polyisocyanurate insulation at R-6, the welded cover is tested to a 40 psf live load, and the slam latch is tested to 50 psf wind uplift, so the hatch holds its seal and stays shut in weather. Counterbalanced compression springs and an automatic locking hold-open arm let one person open it and hold it with one hand. Pick the size that matches your roof opening above.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeries\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDiamond Series, galvanneal steel (RHDG)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCurb\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e14 ga galvannealed steel single wall curb and counterflashing with Diamond Grip\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCover\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e14 ga galvannealed steel formed, welded cover with 22 ga liner, tested to support a 40 psf live load\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInsulation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 in polyisocyanurate in curb and cover, thermal resistance R-6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGasket\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eContinuous weatherproof EPDM sponge rubber, adhesive-backed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSprings\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCounterbalanced compression springs in clear zinc-plated steel cylinders\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLatch\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eClear zinc-plated steel slam latch, inside and outside handles, padlock hasps, tested to 50 psf wind uplift\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHold-open arm\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eClear zinc-plated automatic locking arm with red vinyl grip, one-handed operation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHinge\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHeavy duty clear zinc-plated steel pintle hinge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDoor swing\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOpens 75 degrees\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFinish\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWhite textured powder coat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eSizes\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCurb size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eAccess\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e36 x 30 in\u003c\/td\u003e\n\u003ctd\u003eRHDG-1WT\u003c\/td\u003e\n\u003ctd\u003eLadder\u003c\/td\u003e\n\u003ctd\u003e138 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e36 x 36 in\u003c\/td\u003e\n\u003ctd\u003eRHDG-4WT\u003c\/td\u003e\n\u003ctd\u003eLadder\u003c\/td\u003e\n\u003ctd\u003e163 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e30 x 54 in\u003c\/td\u003e\n\u003ctd\u003eRHDG-2WT\u003c\/td\u003e\n\u003ctd\u003eStair\u003c\/td\u003e\n\u003ctd\u003e188 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e48 x 48 in\u003c\/td\u003e\n\u003ctd\u003eRHDG-5WT\u003c\/td\u003e\n\u003ctd\u003eLadder\u003c\/td\u003e\n\u003ctd\u003e233 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003eLadder-access sizes serve a fixed ladder; the 30 x 54 in stair size is proportioned for a stairwell.

The guardrail criteria are in 1910.29. That is the general-industry rule covering operations and maintenance; construction, alteration and repair work is covered instead by 1926 Subpart M, including when it happens inside an existing building. Confirm the final gate or offset configuration with your AHJ before ordering.\u003c\/p\u003e\n\u003ch3\u003eInstallation note\u003c\/h3\u003e\n\u003cp\u003eOn pitched roofs up to 7:12, mount the hinge side parallel to the slope.
