Question

How to fit replacement spring for Seitz blind? Our Seitz blinds (on 20 yr old Clubman motorhome) won't retract - fly screen element rises up OK, but foil screen won't drop. I cannot see any spring tensioning screw, which you recommend to other enquiries. You have given ref. for replacement spring to another enquiry, BUT its exploded diagram relates to Heiki frame, which doesn't help me. The Seitz blind diagram is a sizing aid only, it also doesn't help me with fitting either. We are concerned about undoing screws and not being able to get it all back together. So - do you have an exploded diagram for Seitz blinds? Or other advice. Thanks.

Answer

On the seitz blind you will need to remove the whole blind from the wall and remove the blind and roller from the housing. If you turn the shaft clockwise then the spring should tighten. if the spring does not tighten then it it likely that you will need to replace the spring, our ref. 135876.
When you have tightened the spring you need to fit the tensioning bush, our ref. 124190, and replace it in the housing without losing the tension (this is fun). In future you should be able to tighten the spring, if necessary, by using a flat blade screwdriver inserted into the tension bush without removing the blind from the housing.
