Dynamic 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.

  • Keeps in shape after repeated belays
  • Str8Jacket intermediate sheath
  • Reduced sheath slippage
  • Does not flatten or become “baggy”
  • Endura DRY treatment on the core

    Chalkline
    Chalk Line is the perfect rope for climbing gyms and indoor climbing walls. It’s special construction makes the rope very durable and resistant to abrasion. Our proprietary Str8 Jacket construction allows the Chalk Line to hold its shape and keeps the cover and core in balance, virtually eliminating sheath slippage. This reduces flat spots and helps maintain the performance of the overall rope. In addition, Chalkline takes the constant falls and belays of the daily gym use perfectly.

    The Chalk Line will provide safe and easy belays through a variety of devices while still maintaining its shape. Gym owners who use Chalk Line love their longevity. It will dramatically reduce down time, rope setting and your annual rope costs.

    Chalk Line is available in 10.8mm, 10.2mm and 9.7mm for top rope and lead ropes. All Chalk Line ropes feature our Endura DRY treatment in the core yarns for added safety. This not only protects you in the gym but also allows Chalk Line to be used in high traffic outdoor walls as well.

    About MAXIM Dynamic Ropes

    Dynamic climbing ropes are the most important piece of gear you have, because they keep you from hitting the ground. Their high elongation absorbs most of the shock in a fall, thereby taking the load off of your body and your anchors. MAXIM ropes are made of 100% high quality nylon and feature a kernmantle construction with twisted nylon cores and a braided nylon cover. MAXIM’s long lasting dynamic climbing lines are designed as a compact rope with high-energy absorption. Each of our dynamic climbing lines offers excellent handling, superior abrasion resistance and high durability.

    Special features of MAXIM dynamic ropes

    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.

    Our Pinnacle and Glider series also feature MAXIM’s TPT (Twill Pattern Technology) which aligns the sheath yarns with the direction the rope moves through your protection. This dramatically reduces rope drag and provides for buttery rappels.

    The Chalk Line gym ropes also feature our Str8 Jacket technology, in which we tightly weave the sheath around a mid-sheath which grips the core. These are the longest lasting gym ropes on the planet.

    Standards for dynamic climbing ropes

    Dynamic climbing ropes are generally certified in three categories; single ropes, half ropes and twin ropes. All of them are certified to the European Standard EN 892 and the international standard UIAA 101. Within these standards, the rope’s construction, sheath slippage, static and dynamic elongation, maximum impact force at first fall as well as the minimum number of falls a rope has to withstand are regulated. Please find more information on climbing rope types and requirements of the standards in our Tech info section.
