Hand rail at 13 cab CMP's
 

Greetings , wondering if there is a drawing or spec for the small diameter round stock handrail mounted outside forward of the cab roof hatch (?) on cab 13 models ? Also , how is it fixed to hatch frame ? Tack welded ? Bolted ?

Some drawings and photos show this item appearing to be fixed to front on right sde and on left side near front on hatch frame side . Does it seem that it was discretionary to whoever fabricated and installed the rail ? Thanks .

Cheers , Johnnie .
