We've installed the ALS light pipe. Richard has installed the lock and tag #2097, key# 3123. Much like the Main beam pipe the ALS one shows a horizontal offset from the upper periscope mirror and is fully offset in the PVC pipe in order to pass through. This may require re-positioning the upper ALS periscope mirror if it is found the beam cannot pass to HAM1 safely.
