Stromberg CL-35 Extend-A-Line RV Ladder Dryer: Parts & Mounts

Stromberg Carlson's CL-35 Extend-A-Line is a removable drying rack with six folding metal arms. It attaches to a compatible RV exterior ladder or to a properly supported mounting bracket, giving towels, swimsuits and other laundry an outdoor place to dry without running a rope across the campsite. The arms fold to one side when the rack is being handled or stored.

Check the ladder and available space

Measure both the ladder-tube diameter and spacing between the ladder's two vertical uprights. The 35-inch model differs from the shorter CL-12, which has 12 inches of usable arm space and a 25-inch storage length. Arm length alone does not establish ladder fit.

Ladder, wall and hitch mounting

The complete CL-35 includes a housing, six arms and an aluminum mounting bracket. For ladder installation, the manufacturer's instructions place the housing against the two ladder uprights with the base supported by a ladder tread before tightening the clamshell grip. For a wall installation, the aluminum bracket needs sound framing or appropriate through-bolting; ordinary drywall anchors are not a substitute for a structural support.

Stromberg offers CL-01 as a separate post for a suitable 4-inch square bumper or 2 × 6-inch A-frame, and CL-02 as a hitch adapter that requires the CL-01 post. Neither accessory is part of the standard ladder-mounted CL-35 purchase.

Before using or storing the rack

1. Confirm ladder dimensions and clearance behind the RV so the arms can pivot without hitting trim or the body.
2. Spread laundry weight across the arms, staying within the manufacturer's per-arm and total limits.
3. Check the clamp and arm pivots before loading the rack. The housing is not designed to serve as a step or ladder handhold.
4. Fold the arms and remove the Extend-A-Line before driving or using the exterior ladder to climb.
