RV Designer's G815 through G855 mounting hardware includes several shapes that use 10 mm ball connections, but they do not occupy the same space or mount at the same angle. Identify the original flat plate, angled bracket, offset bracket or separate stud by exact part number and mounting geometry.

Identify the correct mount by shape

These product numbers identify different mounting arrangements. Check the original hardware's flange, fastener position, ball location and gas-spring socket before replacing a bracket.

MPN Component Size or geometry Package type
G815 Flat bracket Flat mounting plate Pair
G825 Angled / L-shaped ¾ in bracket size Pair
G835 Angled / L-shaped 1 in bracket size Pair
G845 Angled, offset ball 1 in ball offset; 1¼ × 1¼ in base Pair
G855 Separate ball stud 10 mm ball; nominal 1¼ in length Stud accessory
Two different measurements on G845: this bracket has a 1-inch offset of its ball position and a base measuring about 1¼ × 1¼ inches. Those are different dimensions, not alternate lengths for the same feature. Compare its three-dimensional mounting arrangement with the original part.

What to measure on the existing bracket

  1. Compare mounting style: G815 is a flat plate; G825 and G835 are angled mounts, and G845 has an offset ball.
  2. Measure the original bracket: ¾-inch and 1-inch angled sizes are different; do not assume the same ball position.
  3. Check the G845 offset: its ball moves relative to the mounting base, which also has a separate outside size.
  4. Identify a missing stud: G855 is a ball-stud accessory rather than a bracket plate; confirm how it attaches to the existing mount.
  5. Match the socket: verify the original 10 mm ball connection, fasteners and secure mounting surface.

Support the door or hatch before disconnecting a gas spring. Keep your fingers clear of the hinge and replace damaged mounting points before testing the lift.
