2.1 CM LEGREST RECEIVERS - General Installation & Adjustment:
The legrest receivers (MCT or UL Maxx Receivers) are installed into the Center Mount Crosstube using one
of two possible mounting hardware configurations (refer to Fig. 1. and Fig. 2. below). The mounting hardware
will vary depending on the date of manufacture. Both hardware configurations are equally effective. The latest
configuration (Fig. 2.) uses a shorter 30mm shoulder bolt that will be seated inside the crosstube mounting
hole when installed correctly (eliminating the need for lock washers).
NOTE: There are four optional mounting positions (holes) available on the CM Crosstube; Each set of
mounting holes will produce a unique inital legrest angle- refer to Section 3.1, Initial Legrest Angle
Set-Up/ Adjustments. The initial legrest angle must be established PRIOR to starting the installation.
1. Determine the initial legrest angle (mounting holes) to be used on the CM Crosstube (see Section 3.1).
2. Adjust/align the mounting holes in the legrest receivers with the appropriate mounting hole in the CM
Crosstube (per Step 1), ensuring the receivers are adjusted equally at both ends of the crosstube. (Note:
the legrest receivers are width adjustable in 1/2” (13mm) increments in order to align with the seat frame.
3. Align and install the mounting hardware*to secure the legrest receivers in position on the crosstube.
*Note: be certain that the mounting hardware is installed in accordance with the hardware configuration
provided with your LNX CM Legrest (as illustrated in Fig. 1 and Fig. 2. below).
