If you are putting the machine back together without a step-by-step booklet, follow this standard chronological build sequence:
The Base First: Always bolt the bottom floor frame and stabilizer feet together before building up.
The Vertical Mast: Attach the main central upright beam to the base before attempting to attach the top pull-up or lat bars.
The Pulleys & Cables: This is the most difficult step. Always save cable threading for the very end once the physical steel frame is fully tightened. DP Dual Trac 20 (often branded as DP

Deep in the corner of a dusty garage in 1994 sat a cardboard box that promised a "New You." It was the DP Dual Trac 20, a machine of pulleys, steel, and dreams.
Arthur, a man whose last physical feat was reaching for the remote, stared at the Assembly Manual. It looked less like a guide and more like a map to a forgotten civilization. Step one was simple: "Identify all bolts." Two hours later, Arthur was surrounded by a sea of galvanized steel, certain that the factory had included three extra "Part Gs" just to gaslight him.
As he tightened the main upright, the manual whispered secrets of 90s fitness. It wasn't just about the "Dual Trac" technology—the smooth, sliding resistance that supposedly mimicked the grace of a gazelle but felt more like a stubborn mule. It was about the transformation. Every turn of the wrench was a strike against the dad-bod.
By midnight, the machine stood tall—a skeletal monument of cables and vinyl. Arthur pulled the handle. Squeak. He applied the "included lubricant" (which smelled suspiciously like fish oil). He pulled again. This time, it was silent.
He didn't become an Olympic athlete that night, but as he stared at the completed DP Dual Trac 20, he felt the heavy lifting was already done. He had conquered the manual. The workout? That could wait until Monday.
DP Dual Trac 20 Assembly Guide: Step-by-Step Setup & Maintenance
The DP Dual Trac 20 is a classic piece of home gym equipment, known for its versatility in providing both upper and lower body resistance training. Whether you’ve recently acquired one second-hand or are pulling it out of storage, having a clear assembly roadmap is essential for safety and performance.
Since original paper manuals can be hard to find, this guide serves as a comprehensive walkthrough to get your Dual Trac 20 up and running. 1. Inventory and Preparation
Before you begin, clear a 6' x 4' space. Lay out all components to ensure nothing is missing:
The Main Frame: The heavy steel base and upright telescopic bars.
Resistance Rods/Weights: Depending on your specific sub-model, these are the tension components. Cables and Pulleys: The "nervous system" of the machine.
Bench and Seat: The padded sections for sitting or lying down.
Hardware Kit: A collection of bolts, washers, and nylon locking nuts. Required Tools: Two adjustable wrenches (or a socket set). A Phillips head screwdriver. Silicon-based lubricant (for the pulleys). 2. Step-by-Step Assembly Instructions Step 1: The Base Frame
Connect the rear stabilizer bar to the main longitudinal frame. Use the long carriage bolts provided. Tighten these firmly, as this foundation prevents the machine from rocking during use. Step 2: The Upright Support
Bolt the vertical mast to the base frame. This mast usually houses the pulley brackets. Ensure the mast is perfectly vertical before torquing the bolts. Step 3: Bench and Seat Attachment
Align the bench frame with the pivot points on the main base. Slide the pivot bolt through and secure it with a locking nut. The seat should be able to tilt or slide smoothly depending on your model’s specific adjustment pin. Step 4: Cable Routing (The Critical Step) The Dual Trac 20 relies on proper cable tension. Ensure speed is 0
Thread the main cable through the top pulley of the upright mast.
Bring it down through the "floating" pulley (the one not attached to the frame).
Loop it back up or toward the resistance arm.Tip: Ensure the cable sits in the "groove" of every pulley wheel. If a cable is rubbing against metal, it will snap. Step 5: Resistance Arms/Rods
Attach the Dual Trac arms to the sides of the frame. These are usually held by heavy-duty bolts and thick washers to handle the torque of your workout. 3. Safety Check & Calibration Before your first workout, perform the following:
The "Nut Shake" Test: Wiggle the frame. If it rattles, find the loose bolt and tighten it.
Cable Tension: Pull the handles slowly. The movement should be fluid. If it feels "crunchy," a pulley is likely misaligned.
Lube the Tracks: Apply a thin layer of silicone lubricant to the sliding parts of the bench and the pulley axles. Do not use WD-40, as it can degrade plastic pulley wheels over time. 4. Maintenance Tips To keep your DP Dual Trac 20 in top shape for years:
Inspect Cables: Look for fraying or "kinks" in the plastic coating. Replace cables immediately if the steel core is exposed.
Wipe Down: Sweat is corrosive. Wipe the vinyl pads and steel frame after every session.
Tighten Monthly: Constant vibration from weight transitions can loosen nuts over time. Troubleshooting Common Issues
Resistance feels uneven: Check if the cables are crossed or if one pulley is stuck.
Bench is wobbly: Ensure the nylon washers are present at the pivot point; these act as spacers to keep the bench centered.
Section 3: Folding / Unfolding Instructions (Dual Trac 20)
To Fold (Storage):
- Ensure speed is 0.0 mph and machine is stopped.
- Unplug the power cord.
- Lift the deck upward until you hear the locking knob click into the "FOLD" position.
To Unfold (Use):
- Press down lightly on the deck to release tension.
- Pull the Deck Locking Knob outward.
- Lower the deck slowly to the floor until it locks flat.
3 — Install track rails (left and right)
- Place left track rail onto the frame aligning mounting slots.
- Insert bolts through rails into crossmembers; use lock washers or nyloc nuts.
- Repeat for right track rail, ensuring parallel alignment; measure between rails at front and rear — they should match within 2–3 mm.
- Tighten bolts evenly; final torque 20–40 Nm.
6 — Coupler, jack & tongue assembly
- Bolt coupler to tongue using supplied hardware; ensure correct orientation and full engagement of welds/plates.
- Install safety chains between designated tongue mounts; leave enough slack for turning but not dragging.
- Mount jack to the tongue and secure; test operation.
Maintenance Monday (A 30-Second Habit)
Once your DP Dual Trac 20 is assembled, it will run for years with almost zero maintenance. However, once a month, wipe the track rails with a dry rag and apply one drop of lightweight machine oil to the wheel bearings. Do not use WD-40 on the track itself (it attracts dust).
3. Tools Required
Before beginning assembly, ensure the following tools are available:
- Lifting Equipment: Forklift or overhead crane with rated capacity (Unit weight approx. 1,500+ lbs).
- Hand Tools:
- Socket set (Metric and SAE, usually 10mm–24mm).
- Open-end wrenches.
- #2 and #3 Phillips head screwdrivers.
- Flathead screwdrivers.
- Measuring/Terminal Tools:
- Torpedo level.
- Wire strippers/crimpers.
- Multimeter (for electrical verification).
- Consumables: Silicone sealant (high temp), electrical tape, tie wraps.
