Loose Penthouse Roof Latch
Has anyone else had problems with their SMB West penthouse roof latches? I recently found the rear latch is not as snug as the day it was purchased. The SMB Owner's Manual indicates this is normal, but it provides a solution that has not been enough to fix my problem, i.e., tighten the latch screw one or two turns, leaving atleast two thread turns exposed. After two months the rear latch became loose enough to prompt a request for help under warranty from SMB West. They sent a new j bolt which is supposed to be shorter than the original one (I haven't had time to install it yet, and I'll repost when I do).
The photos below show my roof latch configuration and I was wondering if this is standard. Notice the plastic washer (about 1/4" thick) screwed in just off center of the metal base plate. This appears to be a work-around for an over-sized j bolt that has bottomed out at the latch pin and thus can not be screwed in (i.e., tightened) any further. The plastic washer seems to be intended to keep the chain taught by keeping it from spinning. Problem is the strain was sufficient to pull the chain link right past this plastic piece, allowing the chain to stretch out more, further loosening the latch tension. The chain connects the latch to the anchor plate and it provides less tension in one position over the opposite rotated 180 degree position.
