Hidden-Shackle Aluminum Roll-Up Door Lock
Product Information
The TL83 is a two part locking device that leverages the strengths of a hidden shackle lock to provide the highest level of security for a roll-up style door. The hidden shackle design protects your lock from direct access by bolt cutters and hacksaws. Because the TL83 is not permanently installed, it is a portable system that can be used on more than one truck or trailer roll-up door. There are two versions available designed to fit WHITING® or TODCO® roll-up style doors.
The two components of the TL83 are all made of steel, the hockey puck-style lock being hardened steel. The body of the TL83 is ¼” thick solid extruded steel which is welded to the lock. The locking bridge and HASP located in the back of the TL83 is a combination of ¼” steel and ½” steel! TL83’s body is made from solid extruded steel, precision CNC machined, hardened, and then zinc-plated in the U.S.A. to exact standards. The entire assembly is black powder-coated in the U.S.A. for superior rust protection.
The high-security locking solution does not interfere with installing a security seal and includes the PAC-BAND all-weather cover option. The PAC-BAND is a high-grade silicone band that affixes to your lock and covers the cylinder opening preventing debris from entering the cylinder which provides additional protection against the elements.

FAQ's
PACLOCK is proudly Made in the USA with global components. We engineer, CNC machine, assemble, and quality test a majority of our product line at our facility in Los Angeles, California — giving us total control over quality, production speed, and product innovation.
We’re a veteran-owned and woman-owned small business built on American manufacturing and straight-up accountability.
PACLOCK is also the only manufacturer in the world producing Buy American Act (BAA) and Trade Agreement Act (TAA) compliant brass, stainless steel, and aluminum body padlocks.
PACLOCK’s Universal Cylinder System™ (UCS™) gives you total flexibility — choose Keyed Alike (all your locks open with the same key) or Keyed Different (each lock has its own unique key). With our U-PICK!™ option, you can even choose your own key number when ordering keyed alike, or let PACLOCK assign one for you — either way, you get total control and simplicity.
UCS™ works across a wide range of lock types — from padlocks to trailer locks to job box locks — all using the same key system. It’s the best choice for new PACLOCK customers who want simplicity, scalability, and control.
Our Standard Rekeyable (SR) line is ideal for customers who already have padlocks from other brands like Master Lock or American Lock. These locks are designed to be cross-keyable, allowing PACLOCK padlocks to work with your existing keys and key systems.
That means you can upgrade to PACLOCK — and start benefiting from American manufacturing, faster lead times, and better durability — without replacing all your current padlocks. It’s the easiest way to switch without the high cost or hassle.
Already using SR and thinking about switching to UCS™? Reach out — we’ll help you make the transition easy.
