Reversible Tubular Latches: Check the Case Orientation

A reversible tubular latch can suit either door hand, but that does not mean its whole case should be turned upside down. Identify the exact model and read its handing instructions before fitting.

Separate case orientation from bolt reversal

For its passage tubular latch, AHI's installation guide says to keep the arrow pointing up and rotate the latch bolt to suit a right- or left-hand door. Suffolk Latch Company's guide similarly keeps the case's “This Way Up” marking upright while reversing the catch.

These are model-specific examples, not a universal reversal method. If your latch has no clear instructions, do not force the bolt, invert the case by guesswork or assume it is reversible.

Test before closing the door

Suffolk recommends testing with the spindle and knob before installation. Follow your own maker's sequence and use the specified handle and spindle parts. Keep the door open while checking that the fitted handle retracts the latch and that it returns freely. Stop if it sticks or does not retract fully; have an installer check it before shutting the door.

If the latch works open but binds only when closed, see our door-and-strike alignment guide. For selection help, contact Jinnah with the latch model and photos; confirm the exact fit and availability before ordering.
