How to Select a Trailer Hitch

Watch on YouTube →Trailer Safety Chains: How Long Should They Be (Canada)
How long should trailer safety chains be in Canada? Long enough to cross under the coupler and still turn without dragging on pavement. Short enough that they cannot snag, bounce into the road, or leave a giant loop that can catch a curb. This parts-counter walk covers the cross-under habit, slack that works, why too long is also a problem, and which live CURT chain and hook SKUs we keep on this shelf. Pair it with the pin-clip-safety-chains guide, the coupler-latch checklist, and first-tow day before you leave the yard.

All four videos are from the official CURT YouTube channel (@curtmfg). Use them for hitch class basics, install habits, wiring, and ball-mount height so chain length still matches a level, safe hookup.

Lights and plug habits still matter after chains are crossed. A dark trailer is not a finished hookup.

Level coupler height so chains are not fighting a nose-high or nose-low trailer before you roll.
Watch on YouTube →Cross under the coupler first
Safety chains are the backup if the coupler leaves the ball. Cross them under the coupler so they form a cradle. If the coupler drops, that cradle can help keep the tongue off the pavement long enough for you to stop. One chain to each hitch side loop or frame attachment point, crossed under the coupler, is the habit we teach at the counter.
Do not twist chains into a knot and call it done. Do not hang both chains on one loop when two loops are there. Open the pin, clip, and safety chains guide for the wider weekend checklist, then come back here when length and slack are the only question left.
Slack that turns, not slack that drags
Leave enough slack for a full turn without the chains going bar-tight. Too tight and a sharp corner can yank a hook or stress a frame loop. Too loose and the chains drag, spark, or snag on a driveway lip. The sweet spot looks like a gentle X under the coupler with a little give when you steer lock to lock in the yard before you hitch for the highway.
Too long is also a problem. A giant loop that kisses the road every bump is not safer. It can catch a curb, wrap a tire, or slap the pavement until a hook opens. If your chains drag even after a normal cross, shorten the working length with a proper chain setup or use intermediate hangers on a two inch shank so the free length stays off the ground. We do not invent a legal centimetre cutoff here. Your trailer maker, hitch maker, and local rules still win. We teach the practical visual: cross under, turn without dragging, no road-kissing loops.
Step 1
Cross under
One chain each side, crossed under the coupler so they cradle the tongue if it drops.
Step 2
Check the turn
Steer lock to lock in the yard. Chains should not bar-tight or scrape pavement.
Step 3
Kill the drag
If chains kiss the road, shorten the free length or use a chain holder on the shank.
Step 4
Finish the hookup
Latch the coupler, pin the hitch, lights on, then walk the first-tow checklist.
Parts-counter notes on length and strength
| Topic | What we tell shoppers |
|---|---|
| Cross under | Chains should cross under the coupler. That cradle matters more than a pretty parallel hang. |
| Slack | Enough to turn without bar-tight yank. Not enough to drag or catch a curb. |
| Too long | Road-kissing loops are a snag risk. Shorten free length or hang chains off the shank with a holder. |
| No invented cutoff | We do not publish a fake legal centimetre rule. Follow the trailer and hitch makers, plus local requirements. |
| Strength | Chain assembly rating should meet or exceed gross trailer weight on the live card. Confirm before you trust a light utility chain on a heavier trailer. |
| Hooks | Use latching or proper safety hooks that stay closed. Open S-hooks can walk off a loop on washboard roads. |
| Coupler first | Chains do not replace a locked coupler. Walk the coupler latch checklist every hookup. |
| Pin and clip | Hitch pin and clip still belong in the same walk-around. See pin, clip, and safety chains. |

Hook up, then walk away only after the checklist
Chains that look perfect in a straight driveway can drag on the first left turn out of the lot. Do the lock-to-lock check before you trust highway speed. Keep the coupler latched, the hitch pinned, and the lights working. The first-tow day checklist is the calm walk-around we point shoppers to after the hardware is on.
