Power Rack Mounted Leg Extension and Curl Machine - Compact Strength

In this review of the Power Rack Mounted Leg Extension and Curl Machine the bottom line is simple: this attachment is aimed at home gym owners who want a space-saving way to add targeted leg work to a square tube power rack. The single biggest reason to buy is its practical fit and sturdy construction - the unit is built from heavy-duty steel with abrasion-resistant coating and fits racks with 16mm (5/8') holes using the supplied M16 bolt so you can add seated leg extensions and curls without a separate machine.

Key Features

• M16 bolt fit: Designed specifically for square tube power racks with 16mm (5/8') holes so the connector sits securely in compatible racks.
• Adjustable positions: Eight adjustment settings let users customise pad height and range of motion for both leg extension and curl movements.
• Dual mounting for plates: The weight plate holder can be mounted on the front or the sides to accommodate different setups and loading preferences.
• Durable construction: Heavy-duty steel frame with abrasion-resistant powder coating improves longevity and resists corrosion in a home gym environment.
• Comfort pads: Vinyl-covered foam roller pads are sweat and wear resistant, making seated or standing leg work more comfortable.

Who It's For

This attachment suits home lifters and small gym owners who already own a compatible square tube power rack and want a simple way to add leg extension and curl exercises without buying a full-size machine. It is particularly useful for people who need a compact, rack-mounted solution that saves floor space.

Those who should look elsewhere include users whose rack holes are shallower than 57mm overall aperture or users who prefer a guided weight-stack machine; the bolt and non-thread length requirements mean measuring your rack is essential before purchase. Also, if you need an integrated seated bench and back support in the same unit, this attachment is not a full replacement for larger dedicated machines.

Pros & Cons

Pros

• Solid, heavy-duty steel build provides a stable platform for leg extensions and curls.
• Multiple adjustment points and dual plate-holder positions allow tailored fit and loading options.
• Space-saving design mounts to an existing rack, avoiding the footprint of a standalone machine.

Cons

• Requires a rack with at least 57mm aperture depth and 16mm hole diameter; may need spacers if your rack is smaller.
• Some users reported varied experiences with installation ease, so setup can take extra time for certain racks.
