E-Z ShimEZ HS400BP 4" Hinge Shim (15 Pack), Gray, 4 Inch

Easy to install with minimal effort and fuss , they do the job and can be easily cut to size

pricey, yes, does not fit a standard UK 4" hinge, or maybe its because the 4" is now 100mm and the US is still imperial, not checked that though. The saving grace is ease of use, and solid but easily trimmed plastic. slots are generous, so any subtle differences in the hinge manuf. is easily accounted for. Good for the tricky stuff, in my case, replacing old steel 3" with 4"/100mm stainless full bearing hinge, quite a big jump in depth and length, s o good for final fettling.

Have to cut them down to fit a standard hinge.

I could probably have managed without these and used cardboard, but I only needed to adjust the lower hinges and I guess if I want to do some upper ones these would be good as would save removing the door, as is their design. Easy to cut to width required. Good to know they are not going to go soft like card might.

Absoluetly superb product that works perfectly. Quick, easy and permanent solution.

Unfortunately I did not measure and ended up ordering the wrong size so do check first. Purchased the smaller ones and these again we're too large for my UK door hingeEnded up cutting them down which was easy enough. Does the job better than pieces of cardboard

Good but took a long time to arrive

Useful product that works well but very expensive for what it is. Not sure how much better it is that some folded cardboard.
