10.1mm Chalk Line Climbing Rope

Chalk Line is the longest lasting gym rope on the market and was specifically developed for the punishment indoor gyms inflict on rope. Whether you have a small community gym, outdoor climbing wall or a nationally branded gym, the Chalk Line can take the constant falls and belays that all day use can impose.

Key Features:

• Keeps in shape after repeated belays
• Str8Jacket intermediate sheath
• Reduced sheath slippage
• Does not flatten or become “baggy”
• CE Standards: EN 892, UIAA 101
• Single Rope
• 10.1mm ~ 3/8"

Chalk Line will provide a safe and easy belay through a variety of devices while still maintaining its shape. Gym owners who use Chalk Line love the rope's longevity, which saves money by not having to replace the rope as often.

Chalk Line is available in 10.1mm for top rope and lead ropes. This not only protects you in the gym but also allows Chalk Line to be used in high traffic outdoor walls as well.

PRO TIP: Pair with our 1/2" E-Z-TY Rope Clamps!

What is Str8 Jacket technology?

Ropes with Str8 Jacket Core construction feature an intermediate layer of fibers between the core and the cover. These fibers allow the rope to hold its shape better, keep cover and core in balance and therefore, eliminating sheath slippage. This construction is used in MAXIM®’s Chalk Lines to avoid sheath slippage in heavy top rope use.

The core of every dynamic MAXIM Climbing rope is dry treated with our special Endura DRY treatment process, including our indoor gym ropes. This is for the ultimate level of safety protection since nylon loses a lot of strength when wet. In addition, for maximum water-repellency, selected models also feature Endura 2x-DRY and have both a dry core and a specially treated dry cover. Those ropes fulfill the requirements of UIAA water-repellency.
