Spartaks Strength KB2405 5-Post Functional Trainer

Compact frame, full training system. The KB2405 is a 5-post functional trainer on the same 9-gauge steel frame as the rest of the KB24 Series, with an integrated central low row and lat pulldown built right into the rack for efficient training without extra attachments cluttering the floor.

Every KB2405 comes with a single pulley system and a choice of dual 165LB or 220LB weight stacks, upgradable to 300LB. On a single 48" depth frame, the KB2405 is built as a complete cable training system.

Every KB24 rack is built on the same modular platform. As your training evolves, you don't need to sell the KB2405 and start over — we sell the parts to upgrade it directly into the KB2407 or KB2410. Your frame stays, your investment stays, and your rack simply grows with you.

• 5-Post Frame — A compact step up from the standard 4-post design, adding stability without the full footprint of the 6-post models.
• Central Lat Pulldown & Low Row — Integrated directly into the frame for efficient workouts with fewer attachments to manage.
• Single Pulley System — A 2:1 cable ratio for smooth, full-range motion on curls, flys, and rotational exercises.
• Dual Weight Stacks — Choose 165LB or 220LB per side, both upgradable to 300LB, to match your strength level and training goals.
• 9-Gauge Steel Construction — 3.2mm thick steel, roughly 28% thicker than standard 11-gauge (2.5mm), eliminating frame flex during heavy lifts.
• Future-Proof Design — Start with the KB2405 and upgrade later into the KB2407 or KB2410 using shared attachments.
