The Hoist RS-2101 is a selectorized seated dip machine from the ROC-IT commercial line. You sit, press down through adjustable handles, and the seat rocks rearward into a stable finish position. It suits gyms, studios, and home lifters who want the dip pattern loaded from a weight stack instead of bodyweight.
It trains the dip pattern from a seat, with the machine adjusting your position as you press rather than holding you rigid.
Hoist describes the movement plainly: the body starts in a slight forward lean, then rocks rearward to a stable exercise position that naturally mimics the motion of a bar dip. That rearward travel is the point of the whole ROC-IT Selectorized line from Hoist—the seat is part of the rep, not just somewhere to sit.
Hoist also states that the adjustable exercise handles provide proper positioning and reduce excessive shoulder stress and instability. That is the manufacturer's engineering claim about the design, not a measured clinical result.
What muscles does a seated dip machine work? The triceps do most of the work, with the chest and front deltoids assisting. An upright torso keeps the emphasis on the triceps; leaning into the movement shifts more of it to the chest.
Three machines can each advertise a weight stack and mean three completely different things—and they sit side by side in the same category.
On the RS-2101, the stack is resistance. Every pound you pin is a pound you press, and your bodyweight plays no part in the load at all. On an assisted station such as the Hoist Chin/Dip Assist RS-2700, the stack does the opposite: it counterweights you, so a bigger number means an easier set. On parallel bars, there is no number—your bodyweight is the floor, and you cannot train below it.
Almost every listing in this category publishes a load figure, and none of them explains which direction it points. That single distinction decides which machine you actually need.
Choose the RS-2101 when you want the dip pattern loaded precisely from zero upward; choose an assist station when the goal is unassisted bar dips.

Hoist builds the same seated dip station two ways and sells a third machine that trains the movement from the opposite direction. Compare them on how the weight behaves, not on the size of the number. If you want to see every option side by side first, the full tricep machine category lists them together.
The plate-loaded Seated Dip RPL-5101 reaches a higher ceiling for less money. What the RS-2101 buys instead is speed—drop sets and client-to-client changes happen in a second, with no plates to carry. Add it to your cart now, or request a private-invoice quote if you are specifying a full-strength floor.
Hoist lists an optional 5 lbs. Weight upgrade under part code RS-CAGE-NG-OPT1, and it is widely misread as five more pounds of capacity.
Hoist's own line documentation frames the add-on weight system differently: it exists to create smaller weight increments so a wider range of users can progress. On a stack that steps in fixed plates, a five-pound top weight gives you a half-step between two pins—the difference between repeating a session and beating it. The extra ceiling is almost beside the point.
One practical note for anyone specifying equipment: the upgrade changes the frame figure as well as the stack figure, so a facility spec sheet needs the upgraded number, not the base one. The other Hoist arm stations take the same part, including the Triceps Extension RS-1103, so a matched row of machines can share one increment standard.
A good fit
Look elsewhere if
That first exclusion is the one that catches people. This machine does not support your bodyweight in any position, so it replaces the loading of a dip, not the skill of one. If you want a lighter, plate-free way to isolate the same muscle, the Club Line Triceps Extension CL-3103 covers that job instead.
Plan for freight delivery and a fixed installation, not a piece you slide into place.
Hoist's warranty schedule puts the ROC-IT Selectorized line in its Commercial and Light Commercial columns: ten years on frame and body components, five years on structural moving parts, three years on pulleys, bearings and bushings, and one year on upholstery, grips, coatings, belts and cables. Hoist defines Light Commercial as a facility charging no membership dues with no more than 50 users per day — hotels, apartment buildings, training studios and similar sites. Coverage runs to the original purchaser and applies to manufacturer defects only, and Hoist reserves the right to change specifications, design and function at any time.
Hoist designs its RS products to be permanently anchored in position, which is worth knowing before you commit a wall or a floor to it. Orders from Hamilton Home Fitness ship to all 50 states from Tennessee; full shipping and return terms cover the 30-day window, the restocking fee, and the rule that custom configurations are final sale.
Can I order this in a custom color? Yes—Hoist offers custom frame and upholstery colors on the ROC-IT line for pricing and lead times quoted at order. Choosing one moves the machine into final-sale territory, so settle the specification before you confirm.
Is a seated dip machine better than bodyweight dips?
Neither replaces the other. The machine lets you set an exact load and train the pattern well below bodyweight; bar dips build the stability and skill a fixed path removes. Most lifters get more from running both.
Does the RS-2101 train the chest as well?
Some. Hoist positions it as a functional movement for the triceps, and the seated, upright finish keeps the emphasis there. Expect the chest and front delts to assist rather than lead.
How much room should I allow around it?
Use the footprint above as the machine itself, then add clearance for the step-through entry and for a technician to reach the stack cage during service. Anchoring means the position you choose is the position you keep.
Is this suitable for a home gym?
Yes, if the room can take a freight delivery and a permanently placed frame. Buyers should note the warranty tier is decided by how the room is used, not by the model number.
Does the price include assembly?
No. Assembly is arranged separately, and Hoist specifies two people and hand tools for this class of machine. Ask our team when you order, and we will point you to installation support in your area.
Why is this priced above the plate-loaded version?
You are paying for the enclosed stack and single-pin changeover rather than extra loading capacity. In a room where more than one person trains, that changeover speed is usually what justifies the gap.
Specifying a full-strength floor rather than one station? Book a gym design session, and we will map the layout, the traffic flow, and the equipment mix before anything ships.
