Product Features And Advantages：

This Type A metal spring hand gripper consists of knurled aluminum alloy handles and high carbon steel springs, constructed as an integrated screw-free Type A frame. It generates training resistance by compressing the spring when squeezed, targeting grip strength, finger grasping power and forearm muscles. A full range of resistance grades is provided: low-resistance options suit beginners and hand rehabilitation, while high-resistance variants satisfy advanced strength training needs. Equipped with multi-color handles, the gripper is small and lightweight for individual training or matching fitness combo sets, ideal for general fitness, daily hand workout and auxiliary rehabilitation after hand injuries.

Product Characteristics：

1.Knurled Aluminum Alloy Handles for Secure Anti-slip Grip Handles are made of aluminum alloy with surface knurling texture to boost friction and prevent slipping even with sweaty palms. The metal handles have moderate weight for solid holding experience, with various color options available.

2.High Carbon Steel Springs with Stable Rebound & Anti-fatigue Performance The core springs are manufactured from heat-treated high carbon steel, ensuring smooth, consistent rebound after repeated squeezing without fatigue deformation. Springs with different wire diameters are matched to distinct resistance levels for clear force differentiation.

3.Screw-free Integrated Type A Frame for High Structural Stability The one-piece Type A design eliminates loose screws and prevents component detachment during use, delivering robust construction and extended service life.

4.Multiple Resistance Grades Cover All Training Stages Resistance options span entry-level rehabilitation to professional strength workouts, catering to new users, rehabilitation patients, fitness enthusiasts and heavy-duty strength trainers.

5.Ultra-compact & Portable for Anytime Training Small size and light weight allow easy storage in pockets or backpacks, enabling convenient hand workouts at home, in offices or while traveling.

6.Wear-resistant, Low-maintenance & Fully Customizable The metal surface resists abrasion and can be simply wiped clean with a damp cloth. Laser engraving of brand logos on handles and custom handle colors are supported for OEM branding and retail kit matching.

Product Parameters：

Remark: Keep away from sharp objects. High-resistance models deliver intense training force; beginners should apply lighter squeezing strength. Do not use on broken or inflamed skin areas.

Applicable Training Scenarios  

✅ Improve Overall Hand Strength: Train grip, finger and forearm muscles for rock climbing, ball games, weightlifting and other sports requiring powerful hand strength.

✅ Office Daily Workout: Squeeze during work breaks to ease mouse hand and soreness/weakness caused by long hours typing.

✅ Hand Rehabilitation Training: Restore muscle strength after finger/wrist injuries or surgeries; low-resistance models for rehab use (always follow doctor or physical therapist guidance).

✅ Elderly Hand Maintenance: Activate hand muscles to prevent age-related decline of grip power.

✅ Combo Kit Accessory & Promotional Gift: Matched component for fitness equipment sets; suitable as small sports promotional gifts.

Resistance Guide: Low resistance for rehabilitation & new beginners; medium-high resistance for intermediate fitness training; maximum resistance for professional strength enhancement.

Usage Instructions

1.Basic Grip Training Hold the gripper firmly, squeeze inward with all five fingers to bring the two handles close together. Hold the squeezed position for 1–2 seconds, then slowly release back to the original state. Complete 15–20 reps per set, with 3–4 sets in total.

2.Targeted Single-finger Training Engage only partial fingers to squeeze the gripper for targeted strengthening of individual fingers, perfect for rehab users or those with weak finger power.

3.Forearm Coordination Workout Repeat squeezing and releasing motions while slightly flexing wrists to simultaneously activate forearm muscle groups.

Usage Precautions

1.Select appropriate resistance based on personal physical condition; new users shall start with low resistance and avoid overexerting with heavy tension.

2.Stop training immediately if sharp pain occurs in hand joints during exercise.

3.Do not use if suffering from acute joint injuries or inflammation; strictly follow medical advice for rehabilitation training.

4.Avoid dropping, hitting or violently twisting the spring to prevent permanent loss of elasticity.

Frequently Asked Questions：

I.Selection

Q: How to pick the right resistance level?

A: 50–100LB: hand rehabilitation, beginners and female users; 150–200LB: general fitness lovers; 250–350LB: advanced strength trainers and rock climbing enthusiasts.

Q: Can the gripper be used by the elderly or rehabilitation patients?

A: Low-resistance models are available for muscle rehab practice. Users with joint injuries or post-surgery conditions must obtain professional advice from doctors or physical therapists before use.

II.Material

Q: Are the handles made of plastic?

A: Handles are solid aluminum alloy with anti-slip knurling, not plastic; springs are high carbon steel.

Q: Will the spring break easily?

A: It resists fracture under standard proper use. Violent over-squeezing, dropping or impact will cause permanent deformation or breakage.

III. Specification

Q: What does LB stand for? Can it be marked in KG instead?

A: LB (pound) is the standard unit for gripper resistance in the fitness industry. Conversion to KG is available upon request, and KG markings can be laser-engraved on handles.

Q: Is the resistance fixed for each grade?

A: Minor tolerance within the same resistance grade is normal and acceptable per industry standards.

IV. Usage

Q: How many training reps are recommended per day?

A: 3–4 sets of 15–20 reps daily for ordinary users. Avoid excessive training to prevent joint strain.

Q: Can I train both hands alternately?

A: Yes, alternate left and right hand workouts to balance bilateral grip strength.

V.Customization

Q: Is custom logo engraving supported?

A: Laser engraving of brand logos on handles is available subject to minimum order quantity (MOQ).

Q: Can I customize exclusive handle color combinations?

A: Custom handle colors are acceptable for bulk orders meeting MOQ requirements.

VI.Sample

Q: Can I request product samples?

A: Samples are available at the buyer’s cost for sample fee and shipping. Sample charges can be deducted from subsequent bulk order payments per company policy.

Q: How long is the sample lead time?

A: In-stock blank samples ship within 1–3 working days; custom samples with laser logos take 3–7 working days.

VII. Packaging
