TESA TK100 high-security half cylinder

The TESA TK100 half cylinder is a high-security European profile cylinder designed for demanding installations. It incorporates TESA's exclusive Drop Orbital technology, a patented non-copy key, and reinforced protection against common non-destructive opening methods. The manufacturer highlights advanced anti-bumping protection, superior pick resistance, and drill resistance above the maximum grade specified in the European standard. The cylinder also features an anti-extraction rotor, anti-crown bars in the rotor, and a reinforced steel body bar as standard.

This half cylinder version is operated by key from the external side only; the internal side is reduced to 10 mm and does not accept a key. It is available in 8 lengths (External: 30 / 35 / 40 / 50 / 60 / 70 / 80 / 90 mm + Internal: 10 mm) to suit many door configurations. Standard finishes are brass and nickel.

The TK100 half-cylinder features an adjustable cam, allowing the cam position to be oriented to suit different installation configurations. This makes the cylinder easier to adapt to on-site fitting requirements.

As a half-cylinder, this version is key-operated from the outside only and does not accept a key on the inside. It retains the security protections of the TK100 range and can be integrated into a master key system with other TK100 cylinders where required.

TESA also presents the TK100 as an ideal cylinder for master key installations, with high keying capacity and no need for passive pins. It is certified according to EN 1303 and rated for 200,000 cycles.

Commercial notes

Master key system: quotation on request, contact us.

The half-cylinder length must be selected by measuring the external side from the fixing screw centre. The internal side is fixed at 10 mm.

According to the manufacturer's recommendation, once installed, the cylinder should not protrude by more than 1 mm.

A2PRO advice

To select the correct length, measure the distance from the fixing screw centre to the external door edge (side operated by key). If you are unsure about the configuration, the master key system, or compatibility with your installation, it is better to check before ordering.
