A PopUp coupler latches itself as the trailer is lowered onto the ball; a molded guide steers the ball in, and a release cable near the jack handle uncouples it. GN1 and GN3 are straight replacements for 4\" round and square trailer tubes. The SB2 and SB116 are short-bed extended couplers built from extra-heavy-wall tube — the SB116 adds 16\" between cab and trailer nose for more swing and easier hook-up. Both come with release cable and hardware; about a half-hour install.\u003c\/p\u003e\n\u003ch3\u003eOptions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGN1\u003c\/strong\u003e — GN1 — self-latching coupler for 4\" ID round tube, 7\/8\" holes thru both sides (32 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGN3\u003c\/strong\u003e — GN3 — self-latching coupler for 4\" ID square tube, 1\" holes thru both sides (42 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSB2\u003c\/strong\u003e — SB2 — short-bed extended self-latching coupler, 24,000 lb GTW, 1\" holes, extra-heavy-wall tube, release cable and hardware (58 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSB116\u003c\/strong\u003e — SB116 — 16\" extended short-bed self-latching coupler, 24,000 lb GTW, 7\/8\" holes, release cable and hardware (73 lb)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e🚚 \u003cstrong\u003eFreight item:\u003c\/strong\u003e ships by LTL freight due to size and weight.
