MNM Scales ST-20K: 20,000 lb × 1 lb Stainless Kit
A stainless indicator on the floor and a cell in the line is a different 20,000 lb job than a hanging head on the hook. The kit All Scales USA actually stocks in Cypress is the MNM Scales ST-20K — 20,000 lb × 1 lb, stainless SBI-521, two eye bolts, 20 ft cable, $799, ten in stock. Live slug: crane-scale-20-000x1-lb-s-type-ntep-load-cell-stainless-steel-indicator-2-eye. Always MNM Scales. The leftover URL still says ntep-load-cell. Read the live specs, not the slug.

Live NTEP: cell vs assembled kit
Live specifications: indicator is a Brecknell SBI-521, IP65 stainless, peak hold, 0.7 in LED or 1 in LCD. Indicator NTEP SBI-521 CoC 11-119 (indicator only). NTEP (this assembled kit) No — process kit, not a complete legal-for-trade hanging scale. We will not promote the leftover slug into a kit CoC. If a Texas inspector is looking at a hanging sale, this carton is the wrong answer. Start with NTEP in Texas and NTEP legal-for-trade.
Cell in the carton: ST-20K / MS-1-20K alloy-steel S-type, 3.00 ± 0.010 mV/V, 385 Ω / 350 Ω, 120% FS safe overload, 20 ft cable, two eye bolts. Sister cell page: MNM Scales MS-1-20K. Matching kit page: MNM Scales 20,000×1 lb S-type stainless indicator kit. Power: internal AC 100–240 V and 4 Ah rechargeable battery. Ports RS-232 / RS-485. Keep this stainless-indicator carton separate from plastic-enclosure ST-20K kits and from the cell-only carton.
Chooser vs the 20k hanging body
The hanging sibling is the MNM Scales 20,000 lb × 5 lb hanging crane — $998. Coarser digit (5 lb vs 1 lb), one head on the hook, remote, no 20 ft cable to trip on. Pick hanging when the crane is the scale. Pick this ST-20K when you want the cell in a sling or a test frame and the stainless head on a wall. Category guide, not this SKU: S-type crane scale kit buyer’s guide. Leaf: S-type crane kits. Ten-thousand-pound cousin: 10,000 lb crane kit chooser.

What is in the Cypress carton
ST-20K 20,000 lb S-type load cell, two eye bolts, 20 ft cable — live copy names 20 ft, so we will not invent another length.
Brecknell SBI-521 stainless indicator, mounting bracket.
Rechargeable battery and AC power.
Always MNM Scales on this house kit. Peak hold is why fab yards buy it — highest reading held on a lift. We will hang a known mass at 21249 FM 529 Rd if you ask: Houston calibration call. Service: scale calibration Houston. Crane leaf: crane scales. Extra cells and cables: parts, cells & indicators. No ISO 17025. No A2LA. No truck or pit scales.
How Cypress hooks the ST-20K
The ST-20K is the kit we send when a Houston fab shop wants 1 lb on 20,000 lb and a stainless head they can keep out of the grinders. Always MNM Scales. Two eye bolts go in the line. Twenty feet of cable, printed on the live page, runs to the SBI-521. Mount the indicator on a wall, a column, or a desk. Peak hold is the key fab yards actually use — highest reading held while the load is still moving.
We will not tell you the assembled kit is legal for trade. CoC 11-119 is the stainless indicator. The leftover product URL still says ntep-load-cell. Cypress copy on the live PDP says the assembled kit is process. That is the sentence we repeat on the phone. If you need a complete NTEP hanging scale placed in service, this is the wrong carton. If you need a process tension kit with a washable stainless head, this is the carton at $799.
Keep this stainless SBI-521 kit separate from plastic-enclosure ST-20K kits we have sold with other indicators, and separate from the MS-1-20K cell-only page. The live Cypress listing includes the cell, two eye bolts, 20 ft cable, SBI-521, mounting bracket, rechargeable 4 Ah battery, and AC. That is the kit. Do not order the cell-only page and hope the stainless head is in the foam.
Safe overload on the cell is 120% FS. That is not an invitation to hang 24,000 lb. Tell us the heaviest lift. A 22,000 lb proof on a 20k cell is how a shop buys a second cell. Eye-bolt thread and hoist hardware beyond the two eyes in the carton are not assumed. Photograph the existing hardware to pete@allscales.com before we ship if you are matching a worn cell.
RS-232 / RS-485 are on the SBI-521. We will not invent a pinout in this post. If you need a cable, start with scale cables and connectors or call. On-site hook-up in Houston rides with the calibration call page. We do not do truck scales. We do not claim ISO 17025. Gravity, peak hold, and a known mass in Cypress are what we actually do.
The 10,000 lb S-type cousin at $499 is the MS70-10k-tc with a 2 lb digit and an NTEP alloy-steel cell called out on that live page. Different kit, different post. This article is the 20,000 lb × 1 lb stainless-indicator carton only. Clone 20k S-type posts that name LP7515 are not this SBI-521 kit. Do not mix them.
Units on the SBI-521 switch lb, kg, and lb:oz. Checkweighing and counting are on the live function list. Counting a 20,000 lb cell is a process trick, not a parts-counter. Do not buy this kit to count bolts. Buy it to hang, tension, and peak-hold. Always MNM Scales. If the stainless head is more than you need, the 10k MS70-10k-tc at $499 is the cheaper S-type cousin with a 2 lb digit — different post. This article stays on the 20k × 1 lb stainless carton at $799.
Call (832) 766-5410 before you mix a leftover URL that says ntep-load-cell with a Texas inspector visit. We would rather walk you to a complete NTEP device than pretend this assembled kit is one. Photograph the existing cell threads if you are replacing a worn S-type in an already-built frame.
A Houston outdoor hook in the rain is why we specify the IP65 stainless SBI-521 instead of a plastic enclosure. Keep the cell in the line and the head on a wall. That is the whole ST-20K pitch from 21249 FM 529 Rd. Always MNM Scales.
