INSTRUCTIONS FOR THE INSTALLATION AND USE OF LADDER JACK SCAFFOLD BRACKETS – MODEL #2400, #2420 & #2430

Capacity: Two men per staging plus 75 pounds.

Ladder requirements:

Model #2400 Side Rail Steel Ladder Jack - Use on Industrial grade, 250 pound rated Type 1 or 300 pound rated Type 1A ladder aluminum or wood ladders. Do Not Use with Fiberglass Ladders. This style ladder jack should be used only with wooden walk planks. Model #2420 & #2430 Aluminum Rung Style Ladder Jack - Use on Industrial grade, 250 pound rated Type 1 or 300 pound rated Type 1A ladder aluminum or Fiberglass ladders. Do Not Use with Wood Ladders.

Setting the Ladder:

Insure that both feet are secured rmly at ground level. The top section of both ladders should rest at against the building. The feet of each ladder should be set into the ground 3” to 4” when an earthen base is available. If working on a solid base the ladder should be equipped with proper cleats. The top of the ladder should then be tied down to prevent slipping. The ladder must be erected at a pitch of 75  degrees, in accordance with ladder safety standards, so that the distance between the ladder base and the vertical wall is one-quarter the working length of the ladder.

Attaching Ladder Jacks:

Model #2400 Side Rail Steel Ladder Jack: This ladder jack can be installed both on the inside or the outer side of the ladder depending on the distance between the ladder and the work wall. The rectangular bars of the ladder jack attach to the ladder by capturing each of the side-rails of the ladder as well as resting on one of the ladder’s rungs. Be sure that the rectangular bars are placed fully into the ladder’s opening and down onto the rung so as to fully engage the rung. The round hook shaped bars of the ladder jack should then be placed around the side-rails of the ladder, resting above the rectangular bars. Adjust the gusset plate, which is attached to the base of the round bars so that the rectangular bars, which become the support arms for the platform, are parallel to the ground creating a level platform. Secure gusset plate by sliding rmly into the appropriate notch in the center bar.

Model #2420 & #2430 Aluminum 2-Rung and 3-Rung Ladder Jack: This ladder jack can be installed both on the inside

or the outer side of the ladder depending on the distance between the ladder and the work wall. Inspect all scaffold components for damage before each use. Test all working parts and make sure all nuts & bolts are tight before each use. Do not substitute parts. Install ladder jack so that the rung support arms seat fully onto the ladder rungs. Do not use if ladder jack top rung support opening is over 2-1/4 inches. Adjust support arm so the arm is parallel to the ground creating a level platform. Securely tighten the wing nut to prevent slippage during use. Do not use ladder jack if parts are bent, cracked, or damaged. Mark such ladder jacks “DANGEROUS – DO NOT USE” and discard or contact manufacturer.

Setting the platform:

Adjust ladder jack so that walk plank is horizontal. Be sure that the scaffold plank is supported at least 12 inches, but not more than 18 inches from each end and is securely placed in order to prevent slipping. (Do not use extension planks on ladder jack scaffolds) Do not use ladder jack scaffolding beyond a height of 20 feet (16 feet in California) above the oor or ground. Failure to do so could cause injury. Be sure that the ladder jack scaffold complies with local, state and federal safety requirements. When using wooden walk planks the distance between ladders should not exceed 8 feet. The maximum plank length is 10 feet. Use clear straight-grained scaffold grade lumber. Planking should not be less than 2” x 10” nominal thickness. Always use two planks to fully deck the platform arms (18” minimum width).
