Installation Of Square Drop Leg A-Frame Jack On Coupler With Round Hole
Updated 09/18/2013 | Published 09/16/2013
Question:
This information for this jack says that it will fit any standard a-frame coupler, yet it lists the tubing width of 2-1/4 The hole size on my a-frame coupler is right around 2-3/8inch in diameter, which means a 2-1/4inch square tube will not fit through it without modifying the coupler from a round hole to a square hole. Is the measurement given in the specification sections actually referring to the diagonal measurement of the tube?

Expert Reply:
The drop leg jacks that we offer have square tubing. You mentioned that the round hole you have on your coupler is 2-3/8 inches diameter. The tubing on the Bulldog Square, A-Frame Jack, part # BD195318 you referenced measures 3 inches diagonally. you would have to modify the hole in your coupler to make this jack fit.
We do offer a Bulldog Round, A-Frame Jack, part # BD155032. This has a capacity of 5000 lbs and has a 2-1/4 inch outer tube diameter. I would then recommend the Bulldog Detachable Footplate, part # BD018564. I have linked you to an installation video for this jack.
