Needed to put a curtain to aislate the entrance of the house from the rest to avoid heat loss when open the door, sometimes I need to stay with the door open for 10 minutes to atend other neighbours or courier, etc…

The bar sometimes falloff because its the typical adjustable bar.

You dont need to cut the curtain to fit this, simply use magnets, one magnet fit inside the bar holder, and other two in the small discs, put the curtain between two magnets to hold. Now you can close the curtain perfectly.

Used 12x3mm magnets

Hole for magnet its 11,92mm to hold tight.

bar holder end diameter its 32mm, 32,50mm for clearance and better installation

bar holder plastic diameter its 24mm, 24,50mm for clearance and better installation.

If your magnets aren't strong and deataches when open the curtain, simply put another magnet on the top of the last disc.
