Trojan Defender Plus Wheel Clamp – Heavy-Duty Lock for 13–16” Wheels, Anti-Tow Spike Security (SKU: 522000)

Trojan Defender Plus Wheel Clamp – Maximum Anti-Theft Security for Trailers and Vehicles (SKU: 522000)

The Trojan Defender Plus Wheel Clamp is a premium security device designed to immobilize trailers and prevent theft, even from the most determined thieves. With reinforced construction, an integrated tamper-proof locking system, and a brutal immobilizing spike feature, this clamp does more than deter—it actively disables any attempt to tow the trailer while clamped.

Suitable for 13” to 16” wheels and tyre widths up to 235mm, the clamp secures around the wheel using a winding adjustment mechanism for a snug and firm fit. A built-in wheel nut cover plate prevents theft via wheel removal, while hardened spikes inside the frame act as a final line of defence—puncturing the tyre if towing is attempted while clamped.

Key Features:

• Fits 13” to 16” wheels with tyre widths up to 235mm
• Hardened immobilizing spikes designed to deflate the tyre if moved forcibly
• Robust construction with anti-tamper locking mechanism
• Adjustable winding clamp system for secure grip
• Integrated wheel nut cover plate prevents wheel removal
• Highly visible deterrent against theft attempts

Applications:

• Boat trailers and camper trailers
• Worksite utility trailers
• Caravans, light commercial vehicles, and off-roaders

Installation Tips:

• Position the clamp over the tyre, aligning the nut shield disc over your wheel bolts
• Use the winding mechanism to tighten the clamp for a secure hold
• Lock the device using the tamper-proof locking system
• Ensure the immobilizing spike mechanism is in place and the wheel cannot roll

Warning: Immobilizing spikes are intended to puncture the tyre if towing is attempted—use with care and always remove before legal transport.

Trojan Defender Plus goes beyond visual deterrence—it’s a mechanical shutdown system for your wheels. Ideal for serious security applications where “locking it” means “stopping it.”
