Trailer Safety Chains: How Long Should They Be (Canada)

Towing

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 covers the cross-under habit, slack that turns, and the CURT chains and hooks we stock, with free shipping anywhere in Canada.

How we set chain length without dragging or snagging

Cross the chains under the coupler so a failed hitch still cradles the tongue instead of spearing the pavement. Leave enough slack for full turns in a parking lot, then watch for dragging on speed bumps and driveway lips. Strength ratings on the chain and hooks must match the trailer plan. S-hooks, latching hooks, and snap hooks are different grab styles. Confirm the product page rating before you trust a hook on a highway tongue.

Step 1Cross under the coupler every time

Cradled tongue beats a dragging spear.

Step 2Set slack that turns without dragging

Parking-lot lock test, then a slow speed-bump check.

Step 3Match chain and hook ratings to the trailer

Weak hooks cancel strong chain.

Step 4Walk away only after the full latch checklist

Chains are one line on a longer yard checklist.
