JBP-712.1 — Extreme 7-inch support block, single
View JBP-712.1 productStromberg Base Pad Extreme vs Peak: Jack Block Dimensions
Stromberg Carlson makes two molded support-block families for parked RVs. Base Pad Extreme is the wider, lower polycarbonate block often used with hydraulic leveling feet. Base Pad Peak has a narrower top and taller profile suited to the contact area of a compatible scissor, stabilizer or tongue jack. Neither is a substitute for a properly rated jack or a vehicle lifting stand.

Choose the block that suits the jack foot
Extreme — broad top
A round or broad leveling foot must fit securely and centrally on its approximately 10-inch top.
Peak — shaped top
The narrower approximately 5¼ × 9¼-inch contact area suits the particular scissor/stabilizer-jack base format.
Stacking reduces ratings
The maker gives lower capacities when using two blocks stacked together. Do not apply the single-block rating to the stack.
Pads on soft ground
Stromberg permits compatible 1- or 2-inch Base Pads with Extreme blocks for softer ground conditions.
Dimensions and limits are manufacturer specifications, not a universal fitment approval or a vehicle-lifting procedure.

- Verify that the RV maker permits a freestanding support block beneath the particular leveling or stabilizing foot.
- Measure the jack's contact area and the required ground-to-foot height; choose the correct block shape and quantity.
- Use a firm, level surface and place the block directly beneath the appropriate foot.
- Stay within the manufacturer's limit for the exact single or stacked arrangement, and use the RV's standard leveling procedure.
- Remove blocks and store them before travel.
