Conceptronic LBA03 — Security Slot Adapter, Standard Slot, Durable plastic
Adds a 3 × 7 mm slotDurable plastic3M adhesive padBlack
The Conceptronic LBA03 is a security slot adapter that adds a standard 3 × 7 mm lock slot to a laptop, tablet, monitor or other device that has none. You stick it to a flat surface of the device with the 3M adhesive pad in the box, and from then on a standard-slot laptop cable lock can be clicked into it like into a built-in slot. The LBA03 is made of durable high-impact plastic, measures 42.5 × 20.2 × 7 mm and weighs just 2 g, so it disappears on the back or side of a device. In practice it is the simple fix for modern ultrabooks, tablets and displays that left out the lock slot, when you still need to tether them to a desk in an office, classroom, reception or shop.
Compatibility — check before buying:
The adapter gives you a Standard slot only. Standard slot (about 3 × 7 mm, often called a K-Slot), the smaller Nano slot and the tapered Wedge slot (3.2 × 4.5 mm) are three different shapes, and a lock head fits only one of them. So you need a Standard-slot lock for it — our Conceptronic CUSTODIO01BW and CUSTODIO02BWM are Wedge-slot locks and will not fit this adapter. The adapter is only as secure as the adhesive bond: stick it to a clean, flat, rigid surface of the device, never over vents, labels, battery covers or removable panels, and let the bond set before loading it. Conceptronic does not publish a pull-out force. The lock itself is not included. Not sure which lock matches? Send us the device model and we check it.

Frequently Asked Questions
Which lock do I need with it?
Any laptop cable lock made for the Standard slot (3 × 7 mm). Wedge-slot locks such as our Conceptronic CUSTODIO01BW and CUSTODIO02BWM, and Nano-slot locks, have a different head and will not fit.
Can I remove it later?
It is designed to stay: the 3M pad is meant as a permanent bond, which is what makes it hard to pull off. Removing it may leave residue or marks, so choose the position carefully before you stick it.
Where should I place it?
On a flat, clean and rigid part of the housing, away from vents, labels, battery or service covers and anything that can be unscrewed. Clean the area first and let the adhesive set before you attach a lock.
How strong is it?
Conceptronic does not publish a pull-out force for the adapter. Like every slot, it is a deterrent against grab-and-go theft, not a safe — for high-value equipment in public areas, combine it with a locked room or cabinet.
Singular Expert Insight
We suggest the LBA03 when a customer’s new ultrabook, tablet or monitor has no lock slot but company policy asks for every device to be tethered. The black plastic LBA03 is the discreet choice for dark devices; the steel LBA02 is the sturdier, silver option. Pair it with a Standard-slot lock and, for desks without a leg or frame to loop around, the Conceptronic LBA01 desk anchor. See our
security products and
docking stations, many of which have a slot of their own.
