"Over the last year I have changed every handle in the house for these from ERA, using both locking and non-locking types as appropriate. These are quick to fit with a 50mm hole cuttter and 25mm wood bit or hole cutter. The tubular latch included allows you to choose a handle centre between 60 to 70mm. This takes into account variances in the width of door stiles or deep door stops fitted to fire check door frames, etc. You can lock the handle without a key - very useful and convenient but make sure you keep the spare in a key cabinet!"
"The chromium finish although very good has a yellowish tint that clashes with most other chromium finished products that one may wish to fit onto a door. e.g the screwfix escutcheon, and letter box are of a different tint."
