A question about the Magnifax III enlarger

I have a Magnifax III and it's great, but the glass in the carrier wrecks my head! No matter how much I try, I can't keep the dust away from it. I've taken out the glass and it works ok, but does anyone know if you can buy a rail or something to hold down the negs inside the carrier so that they don't curl? Thanks in advance for the help!

I have a Magnifax 4, don't know Magnifax 3 specifically. but the carrier of the IV accepts either glasses or glassless inserts (available for 6x4.5, 6x6, 6x7 and 35 mm). In the UK the place to try would be:
