Z720 Knurled Lever Rose Door Handle Information
Knurled door handles are all the rage these days. Great looks and a concise handle grip give you something stylish and functional and what's more they are affordable. These internal door handles are made from a two part metal construction with an aluminium lever and a zinc rose. The rose is made in two parts incorporating a thread for a more stable fix (not push on cover types). The rose is slightly more generous than most lever door handles by virtue of its 53.5mm diameter compared to most that are 50mm. This larger size is great for covering over old paint lines where door handles were placed previously.
The knurled grip is machined on a lathe using a special tool that generates a consistent raised pattern. This is not a sleeve or an effect of any kind but an actual machined part and is quality checked before gaining approval. Knurling creates a non-slip grip which many customers find useful particularly those with arthritic hands.
Available in a range of colours including satin brass, satin chrome, polished chrome and matt black for a complete match with other door furniture and the most popular colour finishes searched for these days.
These door handles are sprung so extra assistance is given to the levers returning to their natural resting position. The Z720 knurled door handles are supplied with 3 self tapping screws for each side of the door handle and two sleeve bolts that pass through the door and the latch for a more solid fixing.
Cleaning your knurled door handles does not require anything special although please avoid any chemical cleaners and use only a semi dry cloth with a mild soapy solution for best results.
Fixing the Z720 knurled door handles is like any other door handle and is simple and easy to do.
Step 1: Unscrew the rose carefully in the correct direction and withdraw the rose cover over the lever. Please note that overtightening can cause the thread to bind and this will need to be released carefully if that is the case.
Step 2: Place the levers onto the door with the spindle and allow the levers to fall loosely to their true line before then marking the fixing positions for the screws and bolts. Check from the side of the door that the levers look to be inline and are not sloping or at an angle. Fixing interior door handles that are out of line can tighten the lever action causing them to stick.
Step 3: If the holes are not already in the door for the sleeve bolts you will need to drill these through (check the latch has provision for the bolts to pass through before drilling). This just needs to be a clearance hole sufficient for the bolts to pass though. You can then screw clamp the two levers to the door with the sleeve bolts first and then use the self-tapping screws to get a more solid fixing. With the sleeve bolts in place this will be easier to do. When using screwdrivers please ensure a suitable Philips type head is used as the screw heads are smaller to allow them to sit down in the countersunk positions in the rose itself.
Step 4: Refit the rose covers over the levers and tighten in a clockwise direction. To avoid cross threading the rose covers always start it carefully and release in a back and forth direction until you pick up the thread and the rose will then easily tighten to its closed position. The rose does not need to be tightened too hard as it is unlikely to loosen but if it does it is simple to tighten back again. Remember to unlock the rose thread by turning in an anti-clockwise direction.
