Chalk Line Str8 Jacket Core was specifically developed for the extreme punishment gyms inflict on rope. Whether you have a small gym or big gym the Chalk Line can take the constant falls and belays ropes endure in climbing gyms. The Str8 Jacket Core allows the Chalk Line to hold its shape and keep the cover and core in balance which virtually eliminates sheath slippage. This will reduce flat spots and help maintain the performance of the overall rope. The Chalk Line will provide a safe and easy belay through a variety of devices while still maintaining its shape.
