Maximum-Strength Tie-Down Cord for Large Vessels and Commercial Use — 1,000 lb. Tensile Strength
When you need the most holding power in the Seachoice tie-down cord lineup, this is it. The 1/4 in. x 1,000 ft. version tops out at 1,000 lb. tensile strength — 175 lb. more than the 7/32 in. version and 400 lb. more than the 3/16 in. — making it the right choice for larger boats, heavier covers, and high-tension shrink-wrap frameworks. The 8-strand braided polypropylene construction with a knot-holding control core grips firmly under load and holds its shape through repeated use.
At 1/4 in. diameter, this cord is easy to handle, knot, and tension by hand. The 1,000 ft. spool is sized for marinas and boat yards covering multiple vessels, or for boaters who want a full season's supply without running short mid-job. Polypropylene resists moisture, mildew, and UV degradation — built to hold up through the full storage season outdoors.
Key Features
- 1/4 in. diameter × 1,000 ft. spool — maximum strength in the tie-down cord range
- 8-strand braided polypropylene cover with knot-holding control core
- 1,000 lb. tensile strength — strongest in the Seachoice tie-down cord lineup

- White color for high visibility
- Manufacturer Part Number: 50-48021 | UPC: 719249480213
Best Use Case
Best suited for securing boat covers and building shrink-wrap support structures on larger vessels — typically 25 ft. and up — where higher tensile strength and a thicker, easier-to-grip diameter make a real difference. Also the preferred choice for marinas and boat yards that want a single heavy-duty cord for all cover and storage work across a mixed fleet.
Parts Desk Insights
Customers choosing the 1/4 in. version are typically working on larger boats or running a marina where reliability and strength matter more than cost-per-foot. Pair with a Seachoice Boat Cover Support Pole and a Seachoice Boat Cover Tie Down Strap Kit for a complete cover system. For large center consoles, the Seachoice Universal Fit Boat Cover for 22–24 ft. Center Consoles is a natural companion. If a lighter cord is sufficient, see the Seachoice 7/32 in. x 1,000 ft. Tie-Down Cord (825 lb.) or the Seachoice 3/16 in. x 1,000 ft. Tie-Down Cord (600 lb.).
