Schlage 48-310-GRN – Frequently Asked Questions
1) What colors does the Schlage 48-310 construction key come in, and does the color mean anything?
Two colors, green and brown. Color coding is how a jobsite crew tells construction keys apart at a glance, so the key handed to trades on one core system doesn't get confused with another. The 48-310 itself is a cut key for a Schlage small format interchangeable core construction setup, and both colors are the same key product, ordered by color.
2) Is the Schlage 48-310 an actual lock core, or just the key?
Just the key. The 48-310 is a cut key that works a Schlage construction core; it is a replacement part, not a cylinder or a lock. If you need the core itself, that is a separate line item from the key.
3) Is the Schlage 48-310 construction key meant for commercial buildings or residential locks?
Commercial. The 48-310 belongs to a commercial construction keying setup, the kind used while a building is still under trade control and the permanent cores have not gone in yet. It is not a house key blank for a residential entry set.
4) Do I need to have the 48-310 Schlage key cut, or does it ship ready to use?
It ships cut. The 48-310 is supplied as a cut key for the construction core, so no local cutting or code work is needed before it goes on the jobsite ring.
5) Does the 48-310 Schlage key have a handing, or does it matter which door it goes on?
No handing to specify. The 48-310 is non-handed, so there is no left-hand or right-hand version to get wrong on the order. Keys work the core, and the core does not care how the door swings.
