Notes
- Ganter GN 831 size 100, in the symbols and order Ganter prints (no units printed; mm assumed from the decimal-comma values): holding capacity FH 1000 N; b1 25.5, b2 22, b3 26, b4 14, d 4.2; h1 18.5, h2 8.5, h3 21.5, h4 25.5; l1 min 67 (types A and SV) or 74 (type S), l2 min 56 or 63; l3 19.5; l4 min 31 or 38 and l5 min 54 or 61 (coding 2); m1 14.3, m2 7, m3 4, m4 8; r 51; w1 ≈ 5.5 (stroke) and w2 ≈ 12 (A, SV) or 8 (S) (adjustable range). The page does not label any column as hook, bolt, mounting hole or closing, so d = 4.2 is not called a hole size here. It describes the clamping hook as pulling parts together 'by up to 5 mm' while the table lists w1 ≈ 5.5, and never defines 'coding 1 / 2', so these are shown as printed. Only size 100 appeared in the table the filter returned; other GN 831 sizes are not shown.
- McMaster-Carr's draw latch page prints option lists, not part rows: overall length 1-7/16 to 2-3/4 in, overall width 1/2 to 5 in, projection 1/16 to 2-3/8 in, latching distance 3/16 to 1-13/16 in, mounting screws No. 2 to 5/16 in and M3 to M10, and weight capacity bins; strike plate material is listed but no strike plate or hole spacing dimension. The page does not say which values go together; use the part page for a particular latch.
- The Southco numbers are caption values from a draw-latch catalog excerpt hosted by NauticExpo (the host page titles it 'C7 draw latch'): four Ø4.3 mm mounting holes, Ø4 rivets or M4 screws for the small size and Ø5 rivets or M5 screws for the large, clamping force 49 N (small) and 176 N (large). The excerpt did not print part numbers, so which latch each value belongs to is not stated; they are quoted only as read. Southco's own tables were not read.
- Hold-down toggle clamps are on toggle-clamps-hold-down; push-to-open latches on drill-in-push-to-open-latches and southco-93-push-to-close-latch; magnetic touch latches on sugatsune-lamp-touch-latches. No file: the hook, lever and catch shapes are not given as numbers. McMaster-Carr sells draw latches and toggle latch clamps with per-part STEP; linked, not copied.

Questions
What is the holding capacity of a GN 831 size 100 toggle latch?
FH = 1000 N on Ganter's page; stroke w1 ≈ 5.5 and adjustable range w2 ≈ 12 (types A, SV) or 8 (type S).
What mounting hole size does a Southco draw latch use?
The catalog excerpt read prints four Ø4.3 mm mounting holes with M4 or Ø4 rivets for the small size and M5 or Ø5 for the large; its part numbers are not printed, so check the latch's own sheet.
What is the difference between a toggle clamp and a toggle latch?
Hold-down toggle clamps (toggle-clamps-hold-down) press a work piece down; toggle (draw) latches pull a lid or door shut. Both are linked on this page.
