Fine-tune your training without compromising safety. The Forte Weight Stack Adder Pin is designed to provide small, controlled weight increases across nearly all selectorized weight stacks, regardless of fitness equipment brand.

Unlike traditional adder systems that rest on top of the weight stack, this improved design integrates directly into the selector pin location — delivering a more secure, stable, and universal solution for incremental loading.

Available in 2.5 lb and 5 lb options, this adder pin allows athletes, rehab clients, and performance-focused users to make lighter jumps in resistance, supporting steady progress without overloading cables or weight stacks.

Key Features

• Universal Compatibility
  Designed to fit virtually all selectorized weight stacks, making it an ideal solution for mixed-brand commercial gyms, facilities, and home setups.

• Micro-Magnetic Retention System:
  Built-in micro-magnetic technology allows the add-on weight pin to securely adhere to the weight stack when inserted, preventing it from slipping or falling out during use.

• Improved Safety-Focused Design
  The oversized head prevents users from stacking additional weight plates on the pin — eliminating the risk of exceeding the manufacturer-rated capacity of the weight stack or cables.

• More Secure Than Stack-Top Adders
  Unlike add-on weights that rest on top of the stack and can shift or fall, this pin integrates directly into the stack for greater stability and user confidence.

• Precise Weight Increments
  Available in 2.5 lb or 5 lb, allowing for gradual progression, better load management, and safer strength gains.

• Durable Construction
  Built for repeated use in high-traffic environments such as commercial gyms, athletic facilities, rehab clinics, and home gyms.

Ideal For:

• Commercial gyms with mixed equipment brands

• Training facilities and rehab environments requiring smaller weight jumps

• Home gyms looking for safer, universal micro-loading solutions

• Users progressing strength without unnecessary strain on equipment
