you're referring to the broomstick
But of course!
What about placement? Where do you anchor the broomstick and which part of the roof do you support?
Talk about a picture or two being worth a 1000 words.......
Ok - so the MB roof holding tool is a telescoping rod with fixtures on each end to latch onto the roof clamps and latch points to hold it in whatever place you want it.
The broomstick method is simpler - it's designed to allow the weight of the roof to hold it in one place. The quick solution is to cut a stick to the required length and use masking or painters tape to secure it. The more complicated version is to turn and shape the ends so that they wedge into the latch and latch points as well.
With the ignition off, the hydraulics will hold the roof open for about 5 minutes. Open the roof halfway, turn the car off, close the doors with the windows down.
Put one hand on the front edge of the top and gently hold it. When the pressure releases, it will either fall forward or backwards depending on where it is.
The roof has a natural balance point were it will almost hold itself up. You want to find this balance point, and then allow the top to "fall" forward a couple of inches.
Have your partner in crime measure this distance from the latches on the top to the latch points on the windscreen edge. Cut your stick to this length.
Now you can either use tape or shape then ends of the stick. If you take a good look at the latch points, you''ll easily visualize how you need to shape the end to "wedge" it where it will stay secure. If you use tape, be liberal - the roof is so well balanced that no matter how careful you are lubing / cleaning, you will naturally move it backwards enough to remove the force holding the stick in place, and it will fall -point down, in my experience - onto your seat.
There are loads of warning about crushing your hands, fingers, and other assorted dangly bits in the roof. I can easily see this happening when it's under hydraulic power. With no power, don't see how it could happen unless you were really careless. The roof is very well balanced, and you can hold it in pretty much any position you want with one hand.
At some point in time I'll take some piece of telescopic rod and do up a proper brace with fixture to better secure the roof just to play. For random window cleaning and lubing, the broomstick works perfectly fine.
