This page helps you match a replacement Sugatsune touch latch, magnetic catch, knuckle catch or tension catch. It shows where Sugatsune prints each figure to match: type, force, door gap, color letters, strike and screws.
The figures come from the Catches and Latches chapter of Sugatsune's General Catalog 501 and from Sugatsune's product pages. Download the Sugatsune Catches and Latches catalog chapter (PDF, pages 144-223)
Step 1: Find the type and the catalog page
A selection from the chapter; page numbers are the catalog's own and link to Sugatsune's PDF of each page.
| Type | Items | Page |
|---|---|---|
| Magnetic touch latch | ML-30S | 163 |
| Magnetic touch latch | ML-80, ML-120 | 164 |
| Push-to-open door latch | ML-ZN80 | 166 |
| Non-magnetic touch latch | MLC-100 | 169 |
| Non-magnetic touch latch | MC-37 | 171 |
| Sealed magnetic catch | MC-JM45, MC-JM50 | 148 |
| Ultra thin magnetic catch | MC-159, MC-YN001P | 149 |
| Knuckle catch | 6900, 6901 | 174 |
| Knuckle catch | K-CATCH | 175 |
| Tension catch | BCTS, BCT | 178 |
On the Sugatsune product pages we checked, the touch latches are named push latches, for example "Magnetic Push Latch" for the ML-30S/WHT. The index lists the 6900 and 6901 with the knuckle catches; their catalog page (174) calls them rotary catches.
Step 2: Read the force under the name Sugatsune prints
For the items in this guide, the catalog index (pages 144-146) gives one of three measures:
- Magnetic Force for magnetic catches and magnetic touch latches: ML-30S 2.6 lbs (1.2 kg), ML-80 3.5 lbs (1.6 kg), ML-120 5.3 lbs (2.4 kg), ML-ZN80 6.6 lbs (3 kg), MC-JM45 and MC-JM50 6.6 lbs (3 kg), MC-159 8.8 lbs (4.0 kg), MC-YN001P 5.9 lbs (2.7 kg).
- Retaining Force for non-magnetic touch latches: MLC-100 20.2 lbs (9.2 kg), MC-37 17.6 lbs (8 kg).
- Push in Force and Pulling Force (two figures) for knuckle and tension catches.
Product pages may label it differently: the ML-30S/WHT page lists 2.6 lbs and the MC-37/WHT-1 page 17.6 lbs as Holding Force, which Sugatsune's Cabinet Catches and Door Latches page says determines "how much force is necessary to open a door or panel". Compare old and new by the same measure. These are forces, not door weights: of the items here, only the ML-ZN80 page prints a door size and weight.
For the MC-37 the catalog adds: "Constant loading of over 8.8 lbs (4 kgf) or excessive pushing or pulling is not recommended." Where one of our product titles says capacity, as on the MC-37, read the number as the force the catalog names.
Step 3: Push latch gap and release stroke
Sugatsune asks for a gap between door and cabinet frame "for pushing room" (ML-30S, ML-80, ML-120) or "for push space" (MC-37); each drawing labels a release stroke:
| Item | Gap; release stroke |
|---|---|
| ML-30S | 3/16 in. (4 mm), overlay door; 3/16 in. (4 mm) |
| ML-80 | 1/8 in. (3.5 mm), overlay and inset doors; 1/8 in. (3.5 mm) |
| ML-120 | 1/8 in. (3.5 mm); 1/8 in. (3.5 mm) close, 1/8 in. (3 mm) open |
| MC-37 | 1/8 in. (3 mm), overlay door; 1/8 in. (3 mm) |
The stroke itself is printed for some items: 5/16 in. (8.5 mm) for the ML-30S, 15/16 in. (23 mm) for the MLC-100, which the catalog calls a long stroke for thick doors, and 1 in. (25 mm) for the ML-ZN80. The ML-120 page says: "Long stroke for medium size doors." Overlay and inset doors are explained in our guide to concealed cabinet hinges.
The ML-ZN80 push-to-open door latch
The ML-ZN80 page heading adds '(DOOR UP TO 36"X96")', and the first note reads 'For doors up to 36" x 96" with a push force of 11 lbs.' The table headed "Max. Door Specs (Reference)" lists 96-1/16" (2440 mm) height, 36" (915 mm) width and 275 (125 kg) under Weight (lbs). Installation is drawn for inset and overlay doors, with a latch-release stroke of 1/8 in. (3 mm).
Step 4: Color letters and strike versions
- ML-30S: /WHT and /BRN. ML-80 and ML-120: /WHT, /BRN and /BLK. Page 164 notes: "Only ML-80/WHT and ML-80/BRN are ROHS compliant."
- MC-37: the table on page 171 lists MC-37/BLK-1, MC-37/BRN-1 and MC-37/WHT-1 with a floating strike and MC-37/BLK with a fixed strike. Sugatsune says the floating strike models allow easy alignment.
- MLC-100: MLC-100WT and MLC-100BL, with a self-adjusting strike plate.
- ML-ZN80: -WT and -BL (white and black); the item table also lists ML-ZN80-BR.
- MC-JM45 and MC-JM50: WT (white) and BL (black).
- 6900 comes in white only; 6901 in /WHT, /BRN and /BLK. Page 174 asks you to specify the color when ordering. K-CATCH: K-CATCH/WHT-T, white.
Step 5: Screws and the strike or counterplate
Sugatsune's product pages say whether fasteners are included and list their size (pages we read); the strike column is from the catalog pages:
| Item | Screws included; strike |
|---|---|
| ML-30S/WHT | Yes, 3.1 x 13; Counterplate |
| ML-80/WHT | Yes, 3.1 x 13 and 2.7 x 13; Counterplate |
| MC-37/WHT-1 | Yes, 3.1 x 13 and 3.5 x 10; Floating strike |
| MLC-100WT | Yes, 4 x 16; Strike, counterplate |
| ML-ZN80-WT | Yes, 3 x 16 and 4 x 16; Strike plate |
| 6901/WHT | No; 2.5mm or #3 screw; Strike |
| K-CATCH/WHT-T | No; 3mm or #4 screw; Strike |
| BCTS-50 | Yes, 3.8x16; Strike |
For the MC-JM45 and MC-JM50 the counterplate is optional and sold separately: stainless steel MC-JM49 or AS-68, or plastic sealed MC-JMP45 (MC-JMP45WT, MC-JMP45BL). For the MC-159, page 149 notes: "Screws not included, use M3 flat head or equivalent." and "Counterplate MC-159-Plate sold separately." For the MC-YN001P: "Counterplate included."
Knuckle and tension catches: push in and pulling force
The 6900, 6901 and K-CATCH entries share one note: "Grabs and holds doors tightly." For the BCTS (316 stainless steel) and BCT (zinc alloy, chrome finish) tension catches, page 178 states: "Tension force is not adjustable." Same number ending, different forces:
| Item | Push in; pulling |
|---|---|
| 6900 | 2.4 lbs (1.1 kg); 3.5 lbs (1.6 kg) |
| 6901 | 4.8 lbs (2.2 kg); 7.0 lbs (3.2 kg) |
| K-CATCH | 12.5 lbs (5.7 kg); 15.6 lbs (7.1 kg) |
| BCTS-40 | 4.4 lbs (2.0 kg); 2.9 lbs (1.3 kg) |
| BCTS-50 | 5.0 lbs (2.3 kg); 3.9 lbs (1.8 kg) |
| BCTS-70 | 12.5 lbs (5.7 kg); 8.5 lbs (3.9 kg) |
| BCT-40 | 9.7 lbs (4.4 kg); 6.6 lbs (3.0 kg) |
| BCT-50 | 9.0 lbs (4.1 kg); 7.3 lbs (3.3 kg) |
| BCT-70 | 10.1 lbs (4.6 kg); 7.7 lbs (3.5 kg) |
