CUSTOMER MEASUREMENT GUIDE
Measure the holes where your shackles attach.
SHACKLE ATTACHMENT HOLE CENTER TO SHACKLE ATTACHMENT HOLE CENTER.
The measurement label is Shackle Hole Center-to-Center Distance. Measure from the center of the actual hole where a shackle attaches at one location to the center of the shackle attachment hole at the next location.
Existing mounting points
Enter actual shackle attachment hole center locations and distances. Identify each hole A–J as applicable, including a useful location name. Check units, elevations, every side, and the diagonals needed to define your layout.
Planned mounting points
Enter the proposed centers of the future shackle attachment holes, not post centers. These values are preliminary for designs and quotes. Before ordering, the actual attachment-hole positions must be established and you must confirm the final locations and distances.
Review and approve your final measurements
For three- to ten-corner designs, each distance identifies the two holes it connects: for example, Hole A–Hole B. Review the final hole-center layout, exact recorded coordinates/distances, geometry, fabric, corner count, selected hardware and price.
You are responsible for entering, checking and approving those final measurements. Explicitly confirm that the actual hole positions are established, the values are final actual measurements, and you authorize manufacture from them. Review the custom-order policy and electronically sign with your full legal name. If anything is uncertain, keep the design preliminary and correct it before signing.
No independent shop field measurement or per-order dimension sign-off is required. The shop remains responsible for manufacturing to accepted specifications using approved methods and internal quality control. Customer approval does not excuse manufacturing errors, defects or applicable customer rights. Unusual or incomplete designs can still be flagged for review.
Standard reinforced corners, D-rings and heavy-duty webbing remain included once in sail retail; turnbuckles remain separate. Example only; your price is calculated in the builder.
