Hollow-braid polypropylene utility rope on a bulk spool. The hollow construction makes the rope lighter than solid-braid or 3-strand poly at the same diameter, and the polypropylene fiber floats - useful for marine, pool, and dockside work where a sunk line is hard to recover. Yellow is the high-visibility utility color, easy to spot against grass, water, or a debris pile and slow to fade in UV.

• Diameter: 5/16" / Length: 600 ft per spool
• Construction: hollow braid polypropylene
• Safe working load: 135 lb (tensile breaking strength is roughly 5x higher; never load near break strength)
• Floats on water - specific gravity around 0.91
• Rot, mildew, and most-chemical resistant; will not absorb water and stays flexible in cold
• UV-stabilized yellow pigment; two to three year outdoor service life depending on climate
• Splices easily - hollow construction takes a brummel splice without a fid

Use: General utility - clothesline, garden and yard tie-up, light marine tether or dinghy painter, banner and event rigging, light fence-stretch, and bulk tie-down stock between 1/4" decorative and 3/8" working line.

Care tip: Polypropylene weakens steadily under UV. Store the spool indoors or under cover when not in use, and inspect the working section for fuzzing or sun-bleached pale spots - both are signs the strength is gone even when the rope still feels intact. Cut and re-end any section that shows damage.

Knot tip: Poly fiber is slick. Wet knots set better than dry; a bowline holds well, while a clove hitch or rolling hitch needs an extra half hitch to keep from slipping under load. For permanent terminations, whip or back-splice the end to keep the hollow braid from unraveling.
