Universal Roller Shade Pin-End L Bracket
L-shaped replacement bracket for the idler (pin) end of a roller shade, replacing cracked or discontinued brand brackets without changing the tube ends. A closed tapered slot (4.6 mm at the bottom widening to 10.8 mm at the top) self-seats any round spring-loaded idler pin from 5 to 10 mm diameter; the pin axis stands 30 mm off the wall plate so tubes up to 38 mm OD clear it. Four 4.5 x 14 mm vertical slots take #8 pan-head screws for outside mount (wall leg) or inside mount (pin leg) and give 10 mm of height adjustment to level against your existing clutch bracket. 60 x 24 x 56 mm, 4 mm plates with a 6 mm corner web, printed standing so load runs along the layers.
Slotted Hook Window Sash Lift
A replacement hook-style lift for the bottom rail of a double-hung window. It is 60 mm wide, 45 mm tall and projects 26 mm, with a 16 x 10 mm finger pocket under the hook. Two 4.5 mm slots fit #6 (3.5 mm) or M4 pan-head screws at any spacing from 30 to 44 mm, so it lines up with the old screw holes after the original cast lift breaks.
Twin-Horn Blind Cord Safety Cleat
A 80 x 16 x 12 mm twin-horn cleat that screws beside a window frame with two #6 wood screws (4.5 mm clearance holes with counterbored heads), so looped blind and curtain cords can be wound up out of a child's reach. It replaces the small stamped cleats that go missing or snap. Each horn leaves a 6 mm tapered gap for the cord to wrap into.
Sliding Window Track Vent Stop Clamp
A C-clamp block that sits over the raised rail of a sliding window or patio-door track. An M5 bolt in a captured nut locks it in place, so the sash can only open to a set ventilation gap. It is 56 x 28 x 18 mm, has a 13 mm throat that fits rails 2–11 mm thick, uses an 8 mm across-flats drop-in M5 nut slot, and the solid 21 mm jaw works as the stop face.
Casement Window Crank Handle
Replacement folding-style crank handle for casement and awning window operators whose original plastic handle has stripped or gone missing — the mechanism outlives the handle and the OEM part is usually only sold as a whole $40–80 operator. The 26 mm OD hub has a 9.6 mm through bore and two opposed M4 heat-set inserts (5.5 mm bores) so set screws grip any splined, D or round operator stub from 5 to 9.5 mm; 80 mm crank throw, 16 mm dia grip, 105 mm long overall, 44 mm tall. Print in PETG or ASA if the window gets direct sun.
