Shackles: Crosby G-209 / S-209 bow (anchor), G-210 / S-210 D (chain) and G-2130 bolt-type bow, 3/16 to 4 in — dimensions and WLL

What are the dimensions of a 1/2 in or 3/4 in bow shackle and D shackle (pin diameter, inside width, length)? · Standard part · basis: Crosby's own catalog pages 77 (G-209 / S-209 and G-210 / S-210, inches) and 79 (G-2130 / S-2130, mm); a reseller copy of G-209 used as a cross-check; numbers only

Also called: bow shackle dimensions, D shackle dimensions, Crosby G-209, Crosby G-210, G2130 bolt type anchor shackle, screw pin shackle, 1/2 in shackle pin diameter, shackle WLL chart, RR-C-271 shackle, 3/4 shackle dimensions

Exact dimensions. True size, with no tolerance added.

sizes: 53 in table

Notes

Three tables, with Crosby's own letters (A to P) in the order the catalog prints them. The text of the catalog pages does not define the letters (the drawing is an image), so none is interpreted here. WLL is the working load limit in metric tons (t) as printed; Crosby prints a design factor of 6 and a maximum proof load of 2 times the WLL.
G-209 / S-209 and G-210 / S-210 are in inches (page 77): sizes 3/16 to 2-1/2 in for the bow (anchor) screw pin shackle and 1/4 to 2-1/2 in for the D (chain) screw pin shackle. The last two columns are tolerances as printed (G-209: C and A; G-210: G and A); the page does not say whether they are plus-or-minus. G-2130 / S-2130 is the bolt-type (nut and cotter) bow shackle in mm (page 79), 3/16 to 4 in; the last two columns are the tolerances for C and A (page 79 prints the label 'Tolerance +/-'). The page's footnotes mark 3, 3-1/2 and 4 in as individually proof tested with certification (†) and 3/16, 3-1/2 and 4 in WLL values with ‡ (furnished in anchor style only, with eyebolts for handling).
A reseller copy of the G-209 table (kwrs.com) prints different values from Crosby's page 77 in several columns (for example at 1/4 in: E .68 against .78, G 1.14 against 1.28, H 1.66 against 1.84) and is not used. DQ Marine's G-209 table agrees with page 77, so the Crosby figures stand.
In US usage 'anchor' = bow (the rounded body) and 'chain' = D (the straight-sided body). McMaster-Carr files shackles under Federal Specification RR-C-271 and 'for lifting'; the federal spec itself was not read, so no claim is made about its figures.
No file: the body cross-section and the eye profile are not given as numbers in the sources read. McMaster-Carr sells shackles with per-part STEP; linked, not copied.

Questions

What is the pin diameter of a 1/2 in Crosby G-209 shackle?

Column D in the catalog table is 0.50 in for the 1/2 in size, with P = 0.50 in; the page does not define the letters, so read them against Crosby's drawing. G-2130 prints D = 12.7 mm for 1/2 in.

What is the WLL of a 3/4 in screw pin shackle?

4-3/4 t for the 3/4 in G-209 / S-209 and G-210 / S-210 (and for G-2130).

What is the difference between G-209 and G-210?

G-209 is the bow (anchor) screw pin shackle and G-210 is the D (chain) screw pin shackle; Crosby prints a separate table for each (the same WLL at each size).
