Deltech Fitness DF807 Leg Extension Curl Machine (Black)

What weight plates does this machine accept?

This machine accepts standard weight plates with 25mm (1-inch) holes. It does not accommodate Olympic plates with 50mm (2-inch) holes. The solid steel weight bar securely holds standard plates without rattling during use. Most home gym owners prefer standard plates as they're more affordable and widely available than Olympic plates.

How much space do I need for this machine?

The machine measures 147.3cm deep, 76.8cm wide and 87.6cm high. You'll need additional clearance around the machine for safe entry and exit, particularly at the front where users mount and dismount. Allow at least 60cm of clearance on all sides for comfortable use and weight plate loading.

Is assembly difficult and what tools are required?

Assembly typically takes 1.5-2 hours and can be completed by one person. The machine includes forged steel chrome-plated wrenches for assembly - a quality touch not found on cheaper equipment. Instructions include a QR code linking to a helpful assembly video on YouTube, making the process straightforward even for those with limited mechanical experience.

What's the maximum weight capacity for this machine?

Whilst the manufacturer doesn't specify a maximum weight limit, the heavy-duty construction with 40kg frame weight suggests substantial capacity. Users report successfully loading 70kg of plates, though this provides very challenging resistance. The solid steel construction and commercial-grade components indicate it can handle significant loads safely.

Can shorter users operate this machine comfortably?

Yes, the adjustable leg pads accommodate users from approximately 152cm (5 feet) to 190cm (6'3") tall. Both upper and lower pads adjust in and out to ensure proper knee alignment with the pivot point. However, some users find the 28.5cm height at the business end makes mounting and dismounting slightly challenging for those with mobility limitations.

How does the resistance feel compared to cable machines?

This pendulum-based design provides variable resistance - lighter at the start of the movement and heavier at the end. This differs from cable machines which provide more consistent resistance throughout the range of motion. Some users add resistance bands to balance the load curve, creating more even resistance from start to finish.

Does the machine require any maintenance?

The bronze bushing design requires minimal maintenance beyond occasional lubrication of the pivot point. The powdercoat finish resists scratches and corrosion, maintaining appearance over time. Check bolt tightness periodically, particularly after initial break-in period. The high-quality construction means maintenance requirements are minimal compared to cheaper alternatives.

How stable is the machine during heavy use?

The 40kg weight and thick steel construction provide exceptional stability with no wobbling or flexing during use. The wide base and low centre of gravity prevent tipping even during explosive movements. Users consistently praise the rock-solid feel, comparing it favourably to commercial gym equipment costing significantly more.
