Caster top plates: plate size, bolt-hole spacing, hole diameter and mounting height (Blickle, TENTE, Colson, Albion) + 100 × 85 hole template — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/caster-top-plate-patterns/ (sheet CC BY 4.0) Basis: Maker datasheets (Blickle LK / BK-ALST and LMDA-TPA, TENTE ALPHA) and retailer listings of Colson and Albion casters, read in this session; one hole-pattern template plate as a file Catalog version: 2026-10-20 Overall (mm): length 100.0, width 85.0, height 4.0 - A swivel or rigid plate caster bolts to the equipment by four holes in its top plate. The pattern is quoted as the spacing between hole centres, long side × short side; the plate is the outside of the steel. Rows marked mm are the maker's metric table (Blickle, TENTE), rows marked in are US catalogue rows as printed (fractions of an inch). The sources do not say which number is length and which is width, so the order printed is kept. - A pattern can be a slot: Colson's 2 series is listed with bolt spacing 1-3/4 × 3 in on three retail pages, 1-3/4 × 2-13/16 slotted to 3-1/16 on another, and 2-3/8 × 3-5/8 plates are listed 1-3/4 × 2-3/4 slotted to 3. The sources disagree on the second spacing (3, 2-13/16 and 2-3/4 in, the last two with a slot), and the plate is 2-1/2 in on most pages but 2-3/8 in on one, so the slot length and the exact second spacing must be checked on the caster's own drawing. Albion's 4 × 4-1/2 plate is listed 2-5/8 × 3-5/8 slotted to 3 × 3. - Hole diameter: Blickle prints 9 mm (100 × 85 plates) and 11 mm (140 × 110 plates) and TENTE 9 mm; the Blickle 140 × 110 plate spacing is printed as 105 × 75–80, a range, so no template is drawn for it. TENTE prints the long spacing as '80/77', two values, so the TENTE plate is not drawn. The US listings give only the mounting bolt (5/16 in for Colson / Alco, 3/8 in for Albion), not the hole diameter, so no inch template is drawn. - Heights are as labelled by each source: Blickle and TENTE 'total height' (mm), the US listings 'mounting height' (floor to the underside of the plate), 'overall height' or 'load height'. These are not the same measure, so do not compare across rows without checking. Offset (swivel lead) is the horizontal distance from the swivel axis to the wheel axle. - The file is a hole-pattern template: a 100 × 85 mm plate with four Ø9 holes on an 80 × 60 mm rectangle (Blickle LK / BK-ALST 82K, 100K-1, 125K-1). The 100 × 85 plate, 80 × 60 spacing and Ø9 are the published numbers; the 4 mm thickness, 6 mm corner radius and the central 50 × 35 mm aperture are Xem choices. Real plates are pressed steel with a swivel race; none of that is modelled. - McMaster-Carr's caster category is linked for per-part STEP; nothing is copied. Plate and stem sizes of Jarvis, Albion, Colson, Tente, Blickle and others also vary per series, so check the series you buy. caster units wheel Ø × width load height top plate bolt hole spacing hole / bolt offset Blickle LK/BK-ALST 82K mm 80 × 40 230 kg 110 100 × 85 80 × 60 9 40 Blickle LK/BK-ALST 100K-1 mm 100 × 40 320 kg 130 100 × 85 80 × 60 9 45 Blickle LK/BK-ALST 100K-3 mm 100 × 40 320 kg 130 140 × 110 105 × 75–80 11 45 Blickle LK/BK-ALST 125K-1 mm 125 × 40 350 kg 155 100 × 85 80 × 60 9 48 Blickle LK/BK-ALST 125K-3 mm 125 × 40 350 kg 155 140 × 110 105 × 75–80 11 48 Blickle LK/BK-ALST 127K mm 125 × 54 450 kg 170 140 × 110 105 × 75–80 11 55 Blickle LK/BK-ALST 150K mm 150 × 50 500 kg 197 140 × 110 105 × 75–80 11 60 Blickle LK/BK-ALST 160K mm 160 × 50 580 kg 202 140 × 110 105 × 75–80 11 60 Blickle LK/BK-ALST 180K mm 180 × 50 600 kg 223 140 × 110 105 × 75–80 11 65 Blickle LK/BK-ALST 200K mm 200 × 50 600 kg 245 140 × 110 105 × 75–80 11 62 TENTE ALPHA 8370PJD100P62 mm 100 80 kg (160 static) 128 105 × 85 80/77 × 60 9 35 Blickle LMDA-TPA 50G / 50K-FK (central bolt hole) mm 50 × 2×19 80 kg 71 Ø41 round single central hole 10.2 31 Blickle LMDA-TPA 75G / 75K-FK (central bolt hole) mm 75 × 2×25 100 kg 98 Ø55 round single central hole 10.2 34 Colson 2.03256.441 (Global Industrial) in 3-1/2 × 1-1/4 250 lb 4-11/16 (overall) 2-1/2 × 3-5/8 1-3/4 × 2-13/16, slotted to 3-1/16 5/16 bolt (hole not printed) not printed Colson 2.03356.42 (Access Casters) in 3 × 1-1/4 — 4-1/8 (mounting) 2-1/2 × 3-5/8 1-3/4 × 3 not printed not printed Colson 4P20PFS (Access Casters) in 4 × 1-1/4 — 5-1/4 (mounting) listing says 2-1/2 × 3-5/8 'to plate', not labelled as plate size 1-3/4 × 3 not printed not printed Colson 2.05256.445 (Access Casters) in 5 × 1-1/4 — 6-3/16 (mounting) 2-1/2 × 3-5/8 1-3/4 × 3 not printed not printed 5 in caster (Alco Sales 41109-TG) in 5 × 1-1/4 — 6-1/4 (load height) 2-3/8 × 3-5/8 1-3/4 × 2-3/4, slotted to 3 5/16 bolt (hole not printed) not printed Albion 18XS04228S (CasterHQ) in 4 × 2 — 5.63 (mounting) 4 × 4-1/2 2-5/8 × 3-5/8, slotted to 3 × 3 3/8 bolt (hole not printed) 1-11/16 Files elsewhere (not hosted by Xem Studio;
