"Used it to replace a conventional latch on an internal door. No longer need to pull down any lever, just a push or a pull. Had attempted to use a cheaper 3 quid roller bolt but that was just dreadful. It was advertised as adjustable and did have an adjuster but seemed to adjust nothing. This one from Screwfix although a little more expensive, actually works. Adjustment is done using a simple screw and all the internals are visible so you can see the adjustment being made. Great Product."
"This item was disappointing. 1. The adjusting nut needs a very thin spanner to turn it. 2. If you need the roller close in it is necessary to cut down the adjusting bolt to stop it snagging on the roller. 3. The spring also has to be reduced. 4. Roller required extra lubrication to run smooth.
Needs both design and manufacturing improvements to represent good value for money."
