Fit & Project Planning
Compare three ways to plan an 18 inch drawer
Standard side-mount: keep the system straightforward
This product mounts at the sides and uses ball bearings for travel. Choose it where standard closing suits the project and the cabinet can provide the required side mounting surfaces. It is not sold here as an undermount or as the separate soft-close model.
Soft-close side-mount: compare the exact-length alternative
The linked soft-close family includes an 18-inch variant. That is a useful comparison for closing action, but check mounting holes, clearance and installation requirements before changing the hardware on an existing box.
Concealed undermount: plan a different box interface
An 18-inch undermount option is also listed. Its locking devices and under-drawer installation are different from the visible side-mounted rail. Review its own instructions for drawer construction and rear details rather than assuming an existing side-mount box can be reused unchanged.
Planning example: For a ten-drawer project, one pack provides ten left-and-right pairs. When comparing prices across the three systems, compare equivalent pack quantities and included hardware—not a per-pair price against a 10-pair kit.
18 inch drawer slide questions
Does the 18-inch standard slide include a soft-close damper?
This is the standard product, not the separate soft-close option. Use the clearly labeled alternative when soft closing is required.
Does full extension mean the drawer travels beyond its full length?
No overtravel claim is made here. Full extension is about accessing the drawer’s length; extra travel beyond that requires a separately specified feature.
Can I compare these with a 450 mm slide?
Eighteen inches converts to 457.2 mm. Compare the actual closed rail, mounting pattern and required clearance before treating a nominal 450 mm slide as equivalent.
