Does anyone no what size Herzim strip I need
To fill in about 6ins gap were the strip as shrunk
I've tried to measure the thickness I've come up with 12mm I want to cover the gap because their is a awning rail screw visible and I don't want water to get in through the screw cheers Phil.

Can't answer your question but want to comment that the "Herzim" strip is just decorative and does not keep the water out. Your scews should be individually sealed already.

There was a post on this forum recently about filling such gaps (also called "Herzim Strips") - John England posted that you could stretch the existing herzim strip and glue it in place. That was for for a 2' gap I seem to recall. I'm not sure how far you can realistically stretch it. The link is here:

Herzim strip

I had a similar gap and I just bought some off-the-shelf 12mm white herzim strip, it looks Ok from a distance, however it is not actually the same as the Eriba one, which has a double ridge all the way along that (I suppose) centres it in the groove. I'd photograph it to show you, but my Troll's back in the storage unit at the moment. I'll add one when I can.

Thanks for that yes I've just purchased some 12mm Herzam strip from seals +direct it fits in the grooves ok but it does sit out proud of the existing strip so I assume Hymer must use a different thickness of Herzam strip .

Thanks for that ....my only concern was if water could get in through the awning rail screw I've got some Herzam strip it does sit proud of the rail so I may put it in or leave it because it doesn't look great not fitting flush to the existing strip many thanks ....Phil.

Herzim seems to be supplied in 11mm or 12mm generally. Kool Classics sell it in Red, White or Silver and it is 11mm wide. It is, also a different shape from the more generally available, rounded herzim strips. See attached photo

Cheers might try that it does cover the gap and the rail screw but it doesn't look right to me

Thank you M le Pew - correction noted - the stuff we put in the waistband and awning profiles is no longer to be called Herzim by us Eriba types. Makes sense it's a maker's name. Does the "proper' stuff have a name?

Or is like "Hoovers" and, therefore, all those similar profiles have become known as Herzim strips...

Oh dear - just looked and Kool Classics call the proper Eriba stuff... yes, you guessed it, Herzim strip...

£2.20 per metre

And I didn't take it as an admonishment - just amusing as always...

They know how to charge...

They also seem to post things to me by giving it to someone who walks all the way with the parcel. Actually, that would probably be quicker... I know that anything ordered from Hymer by an Eriba dealer takes weeks to arrive.

Rang kool classics today 3 times no answers so left a message and my phone number as requested on the voice recorder ......no phone call back so I can assume they don't want my business very rude way to treat possible customers
