Fcldzz 1/4″ zinc alloy trailer hitch coupler lock – black
After a simple, no-nonsense way to stop someone nicking your trailer, boat or caravan? The Fcldzz coupler lock is built to be practical and hard-wearing — small, solid and does exactly what it should: keep your tow bar secured when you’re not around.
What it is
A trailer hitch coupler lock made from zinc alloy with heavy-duty internal components. It uses a 1/4″ diameter tongue pin with an effective pin length of around 3/4″, so it’ll suit most standard couplers. The lock’s finished in a black electrophoretic coating to resist rust and keep things looking tidy.
Key features and why they matter
- Anti-theft protection: A keyed lock to deter casual theft and tampering — handy for peace of mind at home, the marina or the campsite.
- Robust construction: Zinc alloy body with reinforced internal parts helps put off cutting or forced removal.
- Simple operation: Use the flat key and turn it 5–7 times to open or close — no faffing about with fiddly mechanisms.
- Ready to use: Supplied with two keys, so there’s a spare for the glovebox or a trusted mate.
- Compact and versatile: At roughly 4.4 x 4.6 cm it’s small but effective — suitable for trailers, boats, RVs, trucks and cars.
Practical notes
A couple of things to bear in mind: some listings may mention high-strength steel parts inside for extra durability while the outer shell is zinc alloy. Sizes can vary slightly due to manufacturing tolerances, and photos may look different on different screens, so the black finish might appear a touch different in person.
Typical uses
- Securing a trailer left at a storage yard or on the drive.
- Locking the coupler when a boat trailer is parked by the slipway.
- Extra theft prevention for caravans, motorhomes or work trailers overnight.
- A quick security solution for tradespeople leaving trailers on site.
Installation is straightforward: slot the pin through your coupler’s latch point, insert the lock and turn the key a few times to secure. If you’re unsure whether it’ll fit a particular coupler, measure the tongue and check the 1/4″ pin diameter and the approximate 3/4″ effective length first. If any questions pop up after receiving the item, get in touch with the seller or double-check compatibility before use — better to be certain than faffing about on the forecourt.
What’s in the pack: one trailer hitch coupler lock and two keys. Manufacturer: FCLDZZ. Size: approx. 4.4 x 4.6 cm. Colour: black. A straightforward, solid little bit of kit that makes leaving trailers and towables a lot less stressful.
