ThresholdSill Card is an offline-first door threshold and sill takeoff workbench for finish carpenters, remodel door hangers, accessibility sill crews, and millwork installers. Lock a real rough opening into one glanceable sill-card before you cut stock. COLD START THAT MATCHES THE JOBSITE Open straight to the fullscreen sill-card face—not a marketing carousel. Type opening width, sill height above finish floor, stock thickness, interior and exterior overhangs, and bevel as rise/run or degrees. The card immediately locks net sill cut length, bevel face length, out-to-out stock callout, and a screw schedule with count, gauge, and spacing pattern. LIVE CUT MATH Every field updates cut length and fastener layout as you type, with inch and millimeter paths so crews stay in their preferred units on site. SCREW SCHEDULE BOARD Set fastener gauge, length, count, and equal-space or edge-offset pattern along the locked sill length. Use the printable spacing strip when you lay out on the bench. SEED SILL LIBRARY Drop common residential and commercial setups onto the card in one tap: 36 in interior oak, exterior aluminum with pan, thick stone-capped, low ADA transition, double-door center mullion break, and more. The first session is a real jobsite workflow, not an empty form. PROJECT CARDS AND MATERIAL TAKEOFF Save, rename, duplicate, and pin locked sill faces locally so the crew can reopen yesterday’s openings on site. A material takeoff strip derives sill stock length, pan and flashing length, sealant bead estimate, and screw-bag quantity on its own summary screen. BUILT FOR THE CREW Confirm slope on a simple bevel cross-section diagram of rise, run, stock thickness, and finish-floor reference before cutting. Share a plain-text sill card—dimensions, bevel, screw schedule, and takeoff lines—into crew chat or a job folder. A home-screen widget surfaces the last locked sill width, height AFF, and bevel so your lock-glance matches the saw setup. Settings cover units default, density, and seed reset. Policy and Terms screens are fully written—no dead secondary routes and no placeholder copy. Lock the opening. Pull the cut length and fastener takeoff. Touch the saw last.
