SB212 12″ Offset Square Coupler

Fits trailers with 4 1/2″ ID square tube

Our Part measures 4 1/2″ outside to outside and is manufactured with USA steel.  Make sure it fits your trailer downtube.  Some manufacturers use Import tubes, and many are Not sized consistently or are out of round or square.  PopUp assumes No responsibility for returns when incorrect measurements are taken. Please see return policy.

PopUp Extended Coupler gives you an additional sixteen inches clearance between the truck cab and the trailer nose, and between the truck tailgate and the trailer bulkhead. This gives you more trailer swing and more room for hook-up.  To make your towing experience better yet, this extended coupler is fitted with a PopUp GN8 self-latching coupler.

These units are fabricated using extra heavy wall tubing for maximum strength. They are rated at 24,000 pounds gross trailer weight.

Short Bed Extended Couplers come with all necessary hardware and coupler release cabling.

Installation takes about half an hour.

  • If your trailer doesn’t have a thru pin, drill a hole and install a 1/2″ or larger bolt.
  • Verify that the gussets on the trailer will clear the side rails of your truck.

What our customers are saying

  • “This is a 2019 Ford F-150 with 5’5” bed. I was worried about finding a product to get the clearance I needed to pull my horse trailer . My trailer is almost 79 inches wide . Installed the SB116 16” inch extension coupler on my trailer and I’ve pulled it several trips now and it works great. My trailer pulls great due to load is on the truck where it needs to be. Very well made and love the fact I don’t have to get up in the back of truck or reach over the bedside to hook up and unhook.  The folks at PopUp Towing were great to deal with and answered all my questions.”- Mark G.
  • “We installed a CAG (Connect-Adapt-Go) from PopUp Towing on a truck recently.  It went in very easily.  Instructions were very clear and we are very pleased in the outcome.  We will definitely do more business with PopUp Towing.”- Rick & Jean Horsch
  • “We purchased a CC2 Cushion Coupler by PopUp Towing. I’ll tell you what, after arriving home from the last horse show, we were amazed to find two cans of pop that were left on the dinette table still on the table. Now that’s a smooth ride!”- Larry P.
  • “I was having trouble explaining my issue and determining a solution to my turning issue when towing my gooseneck trailer. A friend of mine said, you should try to call the guys at PopUp Towing as they helped solve his issues. Let me tell you, I spoke with two gentlemen at PopUp if I remember correctly their names were Derrick and Chance, those to guys seem to have more knowledgeable information than anyone I’ve spoken with in this industry. Years of valuable knowledge, and highly recommended if you have similar issues. Thanks again and I absolutely love the new RVGC complete pinbox replacement to allow me to tow my 5th wheel without the bulky 5th wheel hitch taking up my bed space.”- Bill F.
