Compulocks Ledge Lock Slot Adapter for MacBook Air 15-inch (M2 to M5) with Combination Cable Lock
MacBook Air 15"Ledge AdapterCombination Cable LockNo Adhesive
The Compulocks Ledge (MBALDG05CL) adds a security lock slot to the MacBook Air 15-inch (M2 to M5), which has no lock slot of its own, and comes bundled with a combination cable lock so you can tie the laptop to a desk in an office, classroom, library, reception or hot-desk area.
The Ledge is a small silver corner adapter that fits next to the trackpad corner of the MacBook Air 15-inch with the supplied installation kit and tamper-proof screws, without adhesive and without any permanent modification. Once installed, the loop-ended cable wraps around a fixed object and the lock head goes into the Ledge slot. This bundle opens with a code, so there are no keys to lose or hand over.
Before you order: Compulocks makes a different Ledge for each MacBook. This one is for the MacBook Air 15-inch M2 (2023, A2941), M3 (2024, A3114), M4 (2025, A3241) and M5 (2026, A3448) only. Do not confuse it with the 13-inch MacBook Air Ledge (MBALDG04) or the MacBook Neo Ledge (MBALDGN01): they are different adapters.
What's in the Box
- 1 × Ledge lock slot adapter for MacBook Air 15" M2–M5 (silver)
- Installation hardware kit (tamper-proof screws)
- 1 × combination cable lock, loop-ended
What It Means in Practice
- The MacBook can be locked to a desk leg or a fixed cable anchor in seconds, which is the usual requirement in shared offices, schools and retail counters.
- The adapter stays on the MacBook, so locking up each day takes as long as plugging in a cable.
- Compulocks states the Ledge does not affect any MacBook functionality and does not affect opening or closing the lid.
- Compulocks also states that installing the Ledge does not void Apple's warranty.
What Will Not Work
- It does not fit other MacBook models or sizes, and it is not intended for Windows laptops.
- It is a visual and physical deterrent. Compulocks does not present it as a guarantee against determined theft.
- Compulocks does not publish compatibility with third-party MacBook cases or shells; a case that covers the corner where the Ledge sits will get in the way.
Key Features
No adhesive, no drilling
Fits with the supplied hardware kit and tamper-proof screws, and does not alter the MacBook body.
Standard T-bar slot
Low-profile slot that works with standard T-bar cable locks, so other compatible locks can be used later.
Combination cable lock included
Code-operated lock with loop-ended cable in the bundle: no keys to manage.
Lightweight
The adapter itself weighs under 0.1 lb (about 45 g), so the MacBook still slides into a sleeve or bag.

Compulocks states that the Ledge does not affect opening or closing the lid or any MacBook functionality.

Singular Expert Insight · Buyer's Guide
MacBooks have no lock slot, so in shared spaces the Ledge is the clean way to add one without glue or drilling. Pick the Ledge for your exact MacBook and decide keyed or combination by who should open it. For the desk itself, our
docking stations turn the locked MacBook into a full workstation with one cable.
✓ Buy it if you need to secure a MacBook Air 15" M2–M5 in an office, school or public area and want a code instead of keys.
✕ Skip it if your MacBook is a different model or size, or it lives in a case that covers its corners.
