ICE-Lok® Thermally Enhanced Wedgelock Installation Instructions
Step 1: Install ICE-Lok® to Card Module
The patented ICE-Lok® card retainer is designed to be installed onto a card module with a sufficiently sized card tab, with properly machined mounting slots. Figure 1 shows the slot detail on a card tab. Two screws can be inserted into the card tab slots and threaded into the tapped full-wedge of the ICE-Lok. The screws will clamp the ICE-Lok to the card module but will slide in the slot as the ICE-Lok is actuated due to the much higher force generated by the wedging action. Torque should be minimized on the screws during installation so lateral motion of the wedge isn’t prohibited and prevent excessive wear of the coating as the wedge slides.

*Step 1: Install ICE-Lok® 2-56 Only
The ICE-Lok® card retainer is designed to be installed onto a card module with a su ciently sized card tab, with properly machined mounting slots. Figure 1 shows the slot detail on a card tab. Two screws can be inserted into the card tab slots and threaded into the wedge of the ICE-Lok with threaded holes. The screws will secure the ICE-Lok to the card module but will move in the slot as the ICE-Lok is actuated. Torque the two mounting screws to 2 in-lbs. This is the only step in the installation process that is different from that of our other ICE-Lok® wedge locks. Follow the remainder of the steps below.
Step 2: Install Card Module to Chassis
Both a left and right card retainer are required for a single card module. Proper installation must be observed to achieve maximum thermal effectiveness. To verify the correct installation, Figure 2 can be referred to, which shows the proper orientation of the L-bracket features of the ICE-Lok wedges.

Step 3: Apply Installation Torque
Once the card module is installed, the ICE-Lok® card retainers may be actuated to begin clamping the card in place. Care must be taken to balance the actuation between the left and the right ICE-Lok for the greatest thermal effectiveness. It is recommended that the left and the right ICE-Loks be tightened a similar number of turns by first tightening bolt sides evenly, and to “hand-tightness”. Then, when both retainers are tight, the full installation torque of 20 in-lbs for the 375 Series and 12 in-lbs of torque for the 250 Series may be applied to the actuating bolt.
