Model 8004A Rear Delt Pec Fly Machine Wholesale & OEM Supply — Commercial Butterfly Rear Delt / Pec Fly Trainer for Gym Distributors and Fitness Equipment Importers
Product Overview: 8004A Rear Delt Pec Fly Trainer
The 8004A is a dual-function selectorized station that combines pectoral fly and rear-deltoid fly movements in one frame. Its converging arm path targets the chest through forward adduction and the posterior shoulder girdle through rear-delt work, making it a high-utility addition to strength circuits where space, cost, and user independence all matter.

Why a Rear Delt and Pec Fly Station Belongs in a Commercial Lineup
Most strength-floor traffic concentrates on pushing movements: chest press, shoulder press, and assisted dips. Pulling work is often limited to lat pulldowns and rows, leaving the posterior deltoid and the smaller upper-back stabilizers under-trained. That imbalance is one of the most common postural issues among recreational gym users.
The 8004A answers that gap without occupying two separate floor positions. A user can move from chest fly to rear-delt fly in seconds, effectively pairing an anterior movement with its opposing posterior pattern. This setup supports balanced shoulder development and creates a natural transition within an upper-body circuit.
The selectorized stack makes the station suitable for unsupervised use. Members select resistance with a pin, set the movement arm, and begin training without changing plates or asking for assistance. That independence is a meaningful operational benefit in facilities with limited floor staff.
Specifications and Commercial Interpretation
The 8004A’s footprint is larger than that of a compact chest press because the movement requires extended arm travel. Planning teams should account for both the 2030 × 1980 mm base and the additional clearance needed for users entering and exiting the seat.

Replaces two separate machines in some layouts |
Independent listings for similar selectorized fly and rear-delt stations show substantial variation. Market examples include models with 80 kg and 91 kg stacks, assembled heights from roughly 1900 mm to 2050 mm, and gross weights between about 250 kg and 330 kg. Product dimensions across comparable units differ by hundreds of millimeters, and price points range widely depending on stack size, frame construction, and origin.
These comparisons support a straightforward conclusion: buyers should evaluate the 8004A against the full specification rather than a single price line. A lower-cost unit with a smaller stack or lighter frame may appear attractive until installation and durability expectations are applied.
Using the Machine Correctly
Pec fly setup: The user sits facing the movement arms, adjusts the seat so the shoulders remain supported, and places the forearms or hands on the pads. The movement begins with the arms open and the chest gently stretched. A controlled squeeze brings the arms together in front of the chest without locking the shoulders forward. The return phase should be slow enough that the chest stays under tension throughout the set.
Rear delt fly setup: The user sits facing the pad, braces the chest against the support, and grips the handles. The arms move outward in an arc while the torso remains still. The rear deltoids, rhomboids, and middle trapezius provide the work. Users should avoid lifting the chest away from the pad or using momentum to swing the arms.
Proper form on both movements relies on moderate resistance and full control. Heavy loading turns the exercise into a shoulder-joint compensation pattern rather than an isolation movement. The 80 kg stack is well matched to this purpose.

Clear visual demonstration of dual-function value |
The 8004A is particularly effective when positioned between a chest press and a rowing station. That placement encourages users to alternate pushing and pulling movements, creating a more balanced upper-body circuit without increasing staff supervision.
Buyer Questions Answered
Can one machine really perform both movements properly?
Yes, when the movement arms and user position are adjusted correctly. The dual-function design separates the two patterns through body orientation rather than forcing a hybrid motion. Users should receive a short demonstration before switching between them.
Is 80 kg adequate for a commercial fly station?
Yes. Fly movements are isolation exercises rather than heavy compound lifts. Most members use far below maximum stack capacity, and a lighter load often produces better contraction quality.
Does the 8004A replace a cable crossover?
No. The crossover offers variable angles and unilateral control that a fixed-path machine cannot match. The 8004A provides a more guided, user-friendly alternative for general members and beginners.
What ceiling height is required?
The assembled height is 2040 mm. Facilities should add clearance for lighting, ventilation, and safe service access when planning the layout.
Is the machine delivered assembled?
No. It ships crated with an approximate volume of 2.03 m³. Proper handling equipment and trained installers are required for safe unloading and setup.
Which maintenance items should be checked regularly?
Cables, pulleys, pivot bolts, guide rods, and upholstery should be inspected routinely. Keeping these items in good condition preserves movement quality and reduces unexpected downtime.
Can colors or upholstery be customized?
Customization depends on order volume and supplier capability. Buyers should request color samples and written confirmation before finalizing bulk orders.
Wholesale and Distribution Information
