The Hoist CL-3103 Triceps Extension is a single-station tricep extension machine from Hoist's Club Line. You sit with your upper arms wrapped over a fixed pad and press down through a guided arc against the machine's own weight stack. It suits gyms, studios, hotels, and home rooms, adding a dedicated arm station.
The CL-3103 has no selector pin. Hoist built the Club Line around a Slide Select System that removes both the pin and the guide rods a conventional stack rides on, so load is changed by sliding a selector instead of pulling a pin and reseating it.
That reads like a detail until you count how often it happens. One session touches the load a dozen times, and a busy arm station repeats that all day. Nothing can be dropped, bent, or carried off, and Hoist states the design lowers what the stack needs in upkeep.
Do triceps machines need a weight-stack pin? No. A pin is the usual way to select load on a stack machine, not the only one. What matters commercially is how fast and how quietly the weight changes and whether the part doing the work can go missing between members.
Load selection is the thing this category never compares. Listings rank stack size, steel gauge, and cam design, and mention the pin only as a convenience. Hoist calls the Club Line stack a leverage weight system and says its own lab testing measured these machines averaging 30% quieter from the user's position—Hoist's test rather than an independent one, but it explains why a Club Line corner sounds unlike a row of plate stacks. If you are still weighing formats, the wider tricep machine category sets out the alternatives.
Choose the CL-3103 if members will serve themselves on your floor.
Seat height is the fit control on this frame. The arm pad does not move, and the pressing arc is fixed, so where you sit decides where your elbows land and where the work begins.
Hoist fits a gas-spring assisted seat adjuster with a large, easy-to-reach handle, so the seat moves while you stay sitting on it. The stops are numbered, which means a member can note their setting once and hit it again without guesswork.
One honest limit sits alongside that. Hoist publishes no range-of-motion setting for this model, so the starting bend is whatever the pad gives you, and a lifter who wants a shorter or longer arc will not find a control for it here.

Every figure below comes from the product sheet, the live listing, and Hoist's own published documents. Where Hoist publishes nothing, this page says so instead of guessing.
Hoist warranties this product to the original purchaser only and guarantees it free from defects in workmanship and materials under normal use or service. The policy covers manufacturer defects only; full terms sit under the Support link on Hoist's site, and Hoist reserves the right to change product specifications, design, and function at any time. Hoist describes its warranty as one of the best in the industry, which is the manufacturer's own characterization rather than a measured comparison.
Plan the stated footprint plus walking room on the seat side and access behind the stack for service.
How much space does a tricep extension machine need? More than its footprint. You need entry room at the seat, clearance to reach the selector, and a path wide enough to get a crated frame to the spot in the first place.
Hoist is blunt about anchoring. The manual instructs bolting the unit to the exercise floor with bolts of at least four and a half inches and warns that skipping it risks tipping and serious injury. That rules out floating floors and rooms where drilling is not permitted.
The frame stands below the eye line of most standing adults, which is what Hoist was aiming at in designing this line to have a lower profile than its other selectorized ranges. On an open floor, that keeps supervision sightlines clear.
Hoist is not on our free-shipping brand list, so this ships as freight from our Tennessee base to all 50 states. Read the shipping and returns terms before you order, and if you are laying out a full strength line, book a free gym design consultation first.
A good fit if you:
Look elsewhere if you:
That last point is worth stating plainly. Hoist does not publish a maximum user weight for this model anywhere, so facilities with a stated equipment policy should confirm it in writing before ordering. If a single frame has to cover both arm groups, the bicep and tricep machine collection is the better starting point, and Hamilton Home Fitness can talk you through either route.
Hoist covers triceps work three ways on this floor, and they separate on how the load is selected rather than on what the muscle does.
The Triceps Extension RS-1103 is the pick when you train alone and want its rocking user support, and the Preacher Curl/Triceps Extension HD-3100 when one frame has to handle curls as well. Ready to spec this one? Request a quote and we will confirm your build and lead time.
Does the setting on the stack equal the weight at your hands?
No. Hoist prints a weight-ratio page for this machine showing both handles delivering half the selected setting, so the top of the range works out at 100 lbs. at the handles. Set your working weight by what moves, not by the number on the stack.
Is the CL-3103 quiet enough for a shared room?
Quieter than a conventional plate stack, by Hoist's own measurement. The 30% figure comes from Hoist's internal decibel and vibration testing, so treat it as the manufacturer's result rather than a verified third-party benchmark.
How is it different from a cable pushdown station?
A pushdown column lets you swap grips and change angles freely. This frame fixes the arc and supports the upper arm instead, which trades variety for consistency. Facilities usually run both, and the Hi-Lo Pulley CMS-6175-EZG is the hoist option for the cable half.
How are hoist orders placed?
Hoist Fitness runs as a private invoice with us. Add the machine to your cart or contact the team, and we quote and invoice the order rather than processing it as a standard checkout.
Can the frame and upholstery be specified in other colors?
Hoist publishes standard frame and upholstery colors for the Club Line and offers custom colors on request, with pricing and lead times confirmed at the time of order. Be aware that custom imported configurations are final sale under our returns policy.
Will it fit through a standard doorway?
Hoist publishes no crate dimensions for this model, so confirm freight measurements with us before delivery day rather than assuming the assembled figures apply.
Start your order today and put a dedicated triceps station on the floor that members can load without touching a pin. We are an authorized hoist dealer shipping nationwide from Tennessee, and our team can spec the rest of your commercial strength range around it.
