Dormakaba R8146-S-26D-41 – Frequently Asked Questions
1) What applications is the Dormakaba Simplex 8146 best suited for?
The 8146 works for commercial interior doors requiring dual-function capability. Use for offices, server rooms, and storage areas where you need combination entry plus passage mode. The mortise design handles heavy-duty applications.
2) What door thickness and prep does this lock require?
Standard mortise prep fits doors 1-3/8" to 1-3/4" thick. Check the manufacturer template for exact cutout dimensions. Most commercial doors with existing mortise prep can accommodate this lock.
3) How do you determine the correct handing for installation?
Stand on the secure side of the door. If hinges are on your left, order left-hand. If hinges are on your right, order right-hand. The lever and pushbuttons must align with your door swing direction.
4) What finishes are available for the 8146 series?
Common finishes include satin chrome, bright brass, and oil-rubbed bronze. Check current availability as finish options may vary. Match existing hardware in your facility for consistent appearance.
5) What grade rating does this mechanical lock provide?
Simplex mechanical locks typically meet commercial-grade standards for durability and security. The solid construction handles frequent use in office and light commercial environments. Verify specific grade requirements for your project.
6) How do you set and change combinations on the 8146?
Remove the lock from the door to access the combination chamber. Follow the manufacturer's sequence to set your desired code. Use 2-5 buttons in your combination. Clear existing codes before setting new ones.
7) What accessories work with this mortise lock?
Standard mortise accessories include strike plates, cylinder guards, and trim rings. Check our door hardware accessories section for compatible components that work with Dormakaba mortise locks.
8) Can this lock be installed in existing mortise door prep?
Most standard mortise preparations work with minimal modification. Check backset and faceplate dimensions against your existing prep. Some strike plate adjustment may be needed for proper alignment.
9) How do you maintain mechanical pushbutton locks?
Clean buttons and mechanisms with mild soap solution. Apply light machine oil to moving parts annually. Avoid spray lubricants that attract dirt. Check button operation and lever return spring tension during regular maintenance.
10) What other Simplex models offer similar functionality?
The 8100 series offers cylindrical alternatives for different door types. Check our Dormakaba section for other mechanical pushbutton options. Consider your door prep and security requirements when comparing models.
11) Does this lock work in high-moisture environments?
Mechanical locks handle moderate moisture better than electronic units. For high-humidity areas, ensure proper finish selection and increase maintenance frequency. Consider environmental factors when specifying for pools or exterior applications.
12) What are the key measurements needed for ordering?
Measure door thickness, backset distance, and existing mortise cutout dimensions. Confirm door handing and desired finish. Check strike plate requirements for your frame type. These measurements ensure proper fit and function.
