Full Size Truck Model 1200 PDF Installation Instructions

Holding the ladder stops, Part A, upside down and in the unlocked position, slide them onto each end of the cross member, Part B. Repeat the process for the other cross member. The ladder stops are designed to slide the entire length of the cross member. Once in the desired location, lock ladder stops in place by lifting up on the lever. To un- lock, push down on the lever. For purpose of installation position them two feet from either end.

Slide the triangle brackets, Part C, into the driver side front leg, Part D, and passen- ger side front leg, Part E, from the top. The 5/16-18 nuts are to face towards the rail side of the leg. Using the triangle di- mension diagram to the right as a guide, position the triangle brackets 3/4″ from the top of the leg. Tighten the 5/16-18 fasten- ers to 15 foot pounds of torque. Slide the triangle brackets, Part C, into each of the universal rear legs, Part F, from the top. Create a driver side and passen- ger side rear leg by facing the 5/16-18 nuts one direction on a leg and the other direc- tion on the other. Using the triangle dimen- sion diagram to the right as a guide, position the triangle brackets 3/4″ from the top of the leg. Tighten the 5/16-18 fasten- ers to 15 foot pounds of torque.

Place the cross member assembly, Part B, on its side with the WEATHER GUARD® Product logo facing down. Insert the driver and passenger side front leg assemblies, Parts D & E, into the cross member as- sembly by sliding them in from both ends. Now place the second cross member as- sembly, Part B, on its side with the WEATHER GUARD® Product logo facing up. Insert the two universal rear leg assem- blies, Part F, with the 5/16-18 nuts facing up, into the cross member assembly by sliding them in from both ends. STEP SIX Using a torque wrench tighten the 5/16-18 fasteners to 15 foot pounds at the dimen- sion shown in the chart to the right. Col- umn A is for the front assembly and column B is for the rear assembly. Place mounting pads, Part H, on top of the truck bed rails. Cut the notch into the mounting pad. Place the front assembly, from Step Six, onto the truck with the notched ends approximately 1/8″ from the front of the truck bed. NOTE: Some truck beds will not allow the notch to travel all the way forward.

Place clamp block, Part K, on the threaded end of the clamp assembly, Part J. The clamp block has an offset hole. The thick side should face in to- wards the clamp. Use the thin side if extra clearance is needed. Sliding the clamp assembly, Part J, into the front assembly, place them as far away from each other and as close to the ends of the mounting rails as possible. Clamps can not be more than 9.5″ from either end of the mounting rail. Clamp blocks, Part K, are to be flush with the steel underside of the bed rail. Using a torque wrench, tighten the 3/8-16 fasteners in the clamp assembly to 10 foot pounds. For Ford F250/ 350 and some Dodge Dakota vehicles place the front assembly 3″ from front of truck bed. Hold the clamp assem- bly, Part J, in place and slide the mounting rail into the clamp until it is 1/8″ from the front of the truck. With the tailgate closed place the mounting pads, Part H, on top of the truck bed rails. Tape in place the mounting wedge, Part I, on top of the mounting pad using the diagram to the right as a guide.

Set the rear mounting rail, Part G, on top of the wedge and pad 1/8″ from the closed tail gate. Sliding the assembly clamps, Part J, into the rear mounting rail, Part G, place them as far away from each other and as close to the ends of the mounting rails as pos- sible. Clamps can not be more than 9.5″ from the ends of the mounting rails. Clamp blocks, Part K, are to be flush with the steel underside of the bed rail. Using a torque wrench, tighten the 3/8-16 fasten- ers in the clamps to 10 foot pounds. Disassemble the mounting bar, Part L, from the rear assembly hardware kit and reas- semble on the rear leg assembly, from Step Six. Repeat process for other rear leg. With the tailgate open, slide the rear cross member assembly, from Step Six, into the mounting rail channels with the logo facing towards the rear. The driver side and pas- senger side need to slide into the mount- ing rail at the same time in order to avoid binding. Legs can be placed at any loca- tion along the mounting rail. Using a torque wrench, tighten the four 5/16″ hex head bolts to 15 foot pounds.

NOTE: Due to the taper of some truck beds, it may be necessary to shorten the distance between the legs as you slide the assembly towards the front of the vehicle. Tool Box Mounting Procedure If a bed rail mounted tool box is to be in- stalled with the Model 1200 or 1205, use the 1/4″ thick shims, Part M, that are pro- vided in the tool box mounting hardware kit (came with the ATR TM ) along with the “J” bolts (supplied with the tool box). This will insure a level mounting of the tool box on the truck bed rails. Where the mounting rails (Parts D, E, & F) obstruct the use of a “J” Bolt, use a 5/16- 18 x 3/4″ self-tapping bolt, Part N, in its place which is supplied in the tool box mounting hardware kit that came with the ATRTM. Place the tool box in the desired location on the truck and trace the mounting slot in the bottom of the tool box directly onto the mounting rail. Move the tool box out of the way and drill a 1/4″ dia. hole 3/4″ from the inside edge of the mounting rail. (See diagram) Reset the tool box in the desired position and install the 5/16-18 x 3/4″ self tapping bolt and fender washer. The fender washer came with the “J” bolts. If needed, use the 1/4″ shims, Part M, to level the tool box on the truck.
