Transmitter housings
Side-load housings with a standard API thread at the rear — they fit any rig with that connection. Choose the bit end: a Vermeer or Ditch Witch bolt pattern, or a box thread for a threaded bit.

API box thread at both ends for threaded bits, hammers and mud motors — 71 to 165 mm, including a high-flow model.
See specifications→Transmitter housing range
The housing protects the transmitter and holds it straight behind the bit. The rear end is a standard API thread, so the housing fits any rig with that connection — Vermeer, Ditch Witch, TT Technologies and others. The bit end decides which bits you can run: a bolt-on bit with a Vermeer or Ditch Witch pattern, or a threaded bit on a box-box housing. Every housing is side-load, with a hard-faced wear strip along the body. Tell us your rig, thread and transmitter.

The typical rig is a guide by pullback class — what matters is the thread on your drill string and the bit you want to run. TT Grundodrill rigs use TRACTO's own TD or RD rod thread, so the housing goes on with a TD-to-API adapter sub.
