"The two screw holes in the short side of the catch are situated to close to the bolt, If you are skillfull enough to rout out the job and leave enough meat for the screws to fix into you may well find that on screwing in the screw fully it can split out the rebate and jam against the bolt when operating the lever to open or close it, Causing the operation of the bolt lever to be far to stiff. If you remove more meat from the rebate to stop this I have found the screws drop out on the lower bolts and scratch the floor. The plate needs to be 10mm longer and the screw holes placed further away in this longer plate in order to fix this. Especially as it is now deemed ok to sell punters a door claiming it to be solid oak when in fact it is made up of various glulamed timbers which often disintigrate upon finding your pilot hole for your screw close to a glued join. Add to this the fact the screws that come with the product are to soft and round off the posidrive head or just split in the job, And your in for an annoying waste of time gouging out broken screws and supergluing and bodging the job to get everything to function and appear ok. Seems to be the latest trend. Tight penny pinching on engineering and fixings. I find it necessary to carry a complete range of decent fixings to replace the tosh sold with most fittings these days."
