Cellular Grid RV Stabilizer Jack Pad
This 130 x 130 mm pad goes under the small OEM foot of a scissor or screw stabilizer jack on an RV or trailer, so the foot doesn't sink into gravel or soft ground. Any foot up to 120 mm across sits inside the lipped tray. The open 21.7 mm grid cells underneath (8 mm deep) fill with soil and lock the pad in place. Drain notches let rain run out, and a pull tab with a 20 mm finger hole lets you slide it back out from under the jack.
Pinch Weld Jack Pad Puck
A 74 mm dia x 36 mm tall jack saddle puck that protects a unibody car's pinch weld: a 7 mm wide, 9 mm deep slot with a 45 degree lead-in swallows the folded seam instead of crushing it, while a 45 degree self-centring cone socket underneath (58 mm at the mouth, 20 mm at the apex) seats on any round floor-jack saddle or square jack-stand top in that range. Three radial M4 clearance holes (4.5 mm) at 120 degrees take set screws or a bolt so the puck stays on the saddle when you roll the jack away.
