The Tri-Con SD Housings are compatible with the patented FastBack® Direct Pullback System. These housings are heat-treated with chrome-nickel-moly alloy steel just as our bolt-on transmitter housings. The Box by box design provides unmatched versatility and value so you can use your Eagle Claw SD, Iron Fist or bolt-on blades (using a bit body) with one housing. The stainless steel timing mechanism makes clocking the transmitter to the bit a cinch. The straight-through gun-drilled fluid ports make the transmitter housing easy to clean.

FREQUENTLY ASKED QUESTIONS
Short Answer: Replace as soon as you see any signs of wear or mushrooming. This can be as frequent as each shot, depending on jobsite conditions. Consult the user manual.
Correct use: Before and after each bore, inspect the coiled pins, and mating components for wear or deformation. Keep all contact surfaces clean, apply light grease where applicable, and replace pins that show wear to maintain smooth rotation and fast tool changes
Technical details: Coiled pins are designed to protect the Tri-Con connection by absorbing wear during operation. They are purposefully a wear-item to protect the integrity of the Tri-Con Connection.
Incorrect use includes: Reusing damaged or worn pins or allowing debris to build up in the connection. Incorrect use can introduce greater risk of poor fit, difficult tool changes, or reduced connection performance.
Short Answer: A Tri-Con Housing is used to house and protect the transmitter as well as provide steering control during pilot bore drilling.
Correct use: Tri-Con Housings are installed at the front of the drill string during the pilot bore to hold the locating transmitter and allow the operator to steer the bore accurately. They are designed to provide a durable, secure interface between the drill string and cutting tools and as a radio-detection beacon for walk-over locating receivers.
Incorrect use includes: Using a Tri-Con Housing outside of recommended torque specifications or connection sizes or tooling. Incorrect housing sizing in relation to rig torque can introduce greater risk of steering inaccuracy, transmitter damage, connection wear, and possible safety risks.
Short Answer: Tri-Con Housings are compatible with Tri-Con connection tooling designed for matching size and torque ranges.
Correct use: A Tri-Con Housing should be matched to Tri-Con pilot bits and adapters of the same connection size. The housing must also be appropriate for the rig's torque and pullback capacity.
Technical details: Tri-Con Housings use a non-threaded triangular connection secured with coiled pins, allowing fast changes while maintaining high strength. Compatibility is determined by Tri-Con size and the load rating of the drill string.
Incorrect use includes: Mixing Tri-Con sizes, exceeding the housing's load rating, or adapting it to non-Tri-Con tooling. Incorrect use can introduce greater risk of connection failure or premature wear.
