This article covers サンワサプライ(Sanwa Supply) セキュリティワイヤー一体型ダイヤル錠(ブラック) SLE-32S (× 4).
Overview
The Sanwa Supply Security Cable Lock SLE-32S is a practical accessory designed to prevent theft of laptops, tablets, and other portable devices. Unlike traditional key-operated locks, this model integrates the steel cable and the combination lock into a single unit, eliminating the need to carry separate pieces. The 4-digit dial mechanism means you'll never lose a key, and you can reset the combination to any number you like as often as needed. Each cable is 4.4mm thick and 1.5 meters long, providing enough length to wrap around a desk leg, pole, or other immovable object. The cable is coated with nylon to resist rust and to avoid scratching furniture or the device itself. The package contains four identical locks, all in black, making it a cost-effective solution for securing multiple devices at once.
Connectivity & Compatibility
The SLE-32S is designed to work with any device that has a standard Kensington security slot – a small, rectangular hole typically found on the side or rear of business-class laptops, monitors, projectors, and some tablets. It does not require any drivers or software; simply insert the lock head into the slot, turn the dial to set the combination, and it's ready to use. However, not all portable devices include a Kensington slot – many consumer-oriented ultrabooks and tablets omit it. Always check your device's chassis for the slot before purchasing. The cable is fixed at 1.5m with no retractable mechanism, so you'll need a suitably sized anchor point nearby.
Product Info
Sanwa Supply is a well-known Japanese manufacturer of PC peripherals and accessories, offering solid build quality and reliable customer support. The SLE-32S sits in the entry-to-mid tier of security products, delivering straightforward anti-theft functionality without unnecessary complexity. It was released around 2024 and is widely available through online retailers such as Japan. Each pack includes four independent lock units, each with its own combination dial. No batteries or charging required. The warranty is typical for Sanwa Supply accessories: one year from the date of purchase. Pricing for the 4-pack is approximately ¥5,700, which breaks down to about ¥1,425 per unit – excellent value for anyone needing multiple locks. The product comes in simple retail packaging with a brief instruction card showing how to set and change the combination.
Best Use Cases
Business travelers and frequent commuters: When you need to step away from your laptop at a café, co-working space, or on a train, securing it with the cable around a table leg provides a visible deterrent. The lightweight compact design fits easily into a bag. Office environments with shared laptops: Manage a pool of loaner notebooks? Use one lock per machine to keep them physically tethered to desks. Each staff member can set their own combination, simplifying access control. Students in libraries or study halls: Leave your laptop safely locked while you grab lunch or attend another class. Dial locks mean no keys to lose, and you can share a lock with a friend by resetting the code. Who should avoid it: If your device lacks a Kensington slot (common on thin-and-light laptops like MacBook Air, Surface Pro x, etc.), this lock cannot be attached. Additionally, the cable can be cut with bolt cutters, so treat it as a visible theft deterrent rather than a fortress-grade security solution.
