ST1 - Mounting Adapter - Single-Function
This is the standard TE probe mounting adapter.

The ST1 is the most common type of probe mount. It has a single 8 mm port and is commonly used for TE probes and other single-port probes. Most aircraft have ST1 style TE probe ports with 8 mm ports. However, some glider types (LS) have ports with 6 mm ports. If you need a new single-port mount to your aircraft, you'll want an ST1 with an 8 mm port. The ST1 mounting adapter is not currently available with a 6 mm port. If you are adding a TE Probe to your sailplane or motorglider, and you don't ever plan to add additional functions (pitot and static) in the same location - the ST1 is the mounting adapter to buy. If you think you may want to change to triple-probe functionality (TE, pitot and static in a single probe) in the future, then you will want to install a UN or SUN mounting adapter. Select probes with "ST" in their model numbers for use with the ST1 mounting adapter.
