• Use Rating: Residential / Light Commercial / Full Commercial
• Category: Selectorized combo seated arm curl and standing tricep machine
• Why it matters: Combines two high-value arm exercises in one selectorized unit to save space, simplify programming, and support a wide range of users.

Key Benefits

• Two arm stations in one machine: Perform strict seated arm curls and efficient standing tricep extensions on a single selectorized combination arm machine, reducing equipment count while preserving variety.
• Selectorized 150 lb. stack: The 150 lb. weight stack with 5 lb. increments lets beginners start light and stronger users progress smoothly without plate loading or manual changes.
• Self-adjusting compensating arm: The drive arm automatically compensates for arm position, helping maintain correct biomechanics for both curl and tricep movements.
• Multi-grip handle design: Ergonomically formed rubber handle with three different grip options supports varied seated arm curl and standing tricep patterns and accommodates different forearm lengths.
• Comfortable, supported positioning: Seamless upholstery with ABS seat, back, and arm pad dishes plus a five-position seat adjustment help users lock into a stable setup for strict arm work.
• Commercial-grade durability: High Stress 3/16" ASTM A-500 structural steel frame, solid steel weight plates, and military-spec aircraft cable are engineered for continuous use in busy facilities.
• Low maintenance: Nylon-coated cable, sealed ball-bearing pulleys, and precisely machined plates reduce friction and wear, lowering service demands over the life of the machine.
• Clear user guidance: Bright red pull knobs, a red axis of rotation indicator, and an instructional color placard make setup and technique easy to understand for new users.

Description

The ProMaxima Raptor P-3350 is a space-efficient combination arm machine designed for serious biceps and triceps training. In the seated position, users rest the upper arms on the pad and perform controlled arm curls with the ergonomic multi-grip handle. For standing tricep work, the self-adjusting compensating arm and counterbalanced drive arm allow users to step up, set their grip, and extend through a smooth strength curve.

Adjustability is built into the Raptor P-3350 combo seated arm curl machine to accommodate different body types and training goals. A five-position seat adjustment, managed by heavy duty spring-loaded colored pull-pin knobs, helps users align their elbows correctly on the pad for curls or position themselves under the handle for standing tricep work. The red axis-of-rotation indicator further guides alignment to encourage proper joint tracking and safer loading.

The selectorized weight stack provides quick load changes between arm curl standing tricep exercises. Solid steel plates are machined precisely within an ounce of their stated weight. A tethered magnetic selector pin runs through the full stack to set resistance, and the system allows small 5 lb increments so users can progress gradually. The 150 lb. stack is accessible from the seated position and fully enclosed with form-fitted outer and inner shields for user safety and a clean appearance.

Like other Raptor selectorized units, the P-3350 uses a cable system built around 1/4" thick, 4,800 lb. test military-spec galvanized aircraft cable finished with a tough 3/16" nylon coating. Manual tension adjusters on the machine keep cable slack under control. All pivoting axes ride on radial bearings, and the cable path passes over 4" and 6" solid fiberglass-reinforced pulley wheels with oil-dipped double-sealed racer ball bearings. Pulleys are sealed against moisture and dust to support long service life and smooth, quiet operation.

The frame structure consists of High Stress 3/16" ASTM A-500 grade B structural steel tubing (11 gauge) in 2" x 4" and 2" x 3" sizes on uprights, with 2" x 2" tubing used on cross members and benches. Guide rods are 1" CCRO ANSI 1045 solid steel, hard chrome-plated with a tensile strength of 75,000 psi, helping the weight stack travel smoothly and reliably. All welds are ground down and stress tested for safety and a professional finish.

Users benefit from heavy-duty 40 oz commercial marine Naugahyde upholstery, approximately 85% mildew resistant, over high-density closed cell foam supported by thick plywood backing for stable support. Urethane foam grades HR-125 and HR-150 are used in high-compression areas for comfort and long-term shape retention. ABS protective dishes around the seat, back, and arm pad help prevent damage from repeated use, while natural rubber handgrips and a custom-formed handle enhance comfort and grip security.

Custom color powder coat paint is applied using a three-stage pre-paint process. Steel is pellet-blasted in a state-of-the-art system to clean and prep the surface, then preheated before magnetic powder is applied and baked for a hardened, long-lasting finish. The Raptor P-3350 combination arm machine exceeds applicable ASTM requirements for strength equipment, giving owners confidence in its construction and performance.
