Derkriy Dog Runner Trolley System, 30.5 m Outdoor Cable for Large Dogs

Derkriy Dog Runner is an outdoor dog trolley system designed to give dogs room to move in a yard or at a campsite, with a 100 ft (30.48 m) run cable and a 10 ft (3.048 m) tie-out cable.

• For dogs up to 250 lb (113.4 kg) — gives larger dogs a defined outdoor running area.
• Vinyl-coated cables resist rain and rust — made for outdoor activity.
• Metal shock-absorbing spring — helps reduce the force of sudden stops and fast movement.
• 360° swivel clips made from zinc alloy — designed to reduce tangling and prevent the latch from coming loose.
• Reflective coating — makes it easier to keep an eye on your dog at night.

This trolley system is made for outdoor use when you want your dog to move around while remaining connected to a running line. Set it up in a yard or take it along for camping, picnics, and other outdoor activities. The trolley pulley travels along the cable, while an adjustable turnbuckle helps limit sag and keep the pulley moving smoothly.

What helps reduce jolts while your dog moves?

A metal spring on the runner lead absorbs some of the tension created by fast movement, sudden stops, and jerks. This cushioning feature is designed to reduce abrupt pulling on your dog as it moves along the line.

• The spring is fitted to the runner lead.
• The cable’s reflective coating helps with visibility in low light.

How are tangles and cable sag addressed?

The zinc alloy clips have a 360° rotating latch to allow movement without the lead twisting as easily. Their tightening design helps prevent the latch from coming loose during activity, while the adjustable turnbuckle helps keep the trolley cable from sagging.

• The trolley pulley slides along the running cable.
• Rotating clips are designed to reduce tangling during play.

What comes with the Derkriy Dog Runner, and how is it set up?

The set includes the cables and trolley-system components, a durable Oxford storage bag, and installation instructions. The components pack into the bag for transport, and the system can be installed by one person using the included instructions.

• Use it for outdoor activities such as camping and picnics.
• The vinyl coating on the cables is rain- and rust-resistant.
