Frequently Asked Questions (FAQ)
Q1: How does the "Automatic" function work for this flush bolt?
A: This model features an automatic latching mechanism. In a double-door setup, opening the active (operating) door automatically retracts the bolts on the inactive door. When the active door is closed, the bolts on the inactive door automatically extend into the frame and sill strikes to secure it, eliminating the need for manual operation.
Q2: Why does the description say it must be "used in pairs"?
A: To ensure the inactive door leaf remains stable and secure, this automatic flush bolt requires one unit installed at the top and one at the bottom of the door. Using a single bolt may cause the door to warp or become insecure over time.
Q3: Can I use this automatic flush bolt on a single, standalone door?
A: No. This product is specifically designed for double-door applications where it coordinates with an active door. It relies on the movement of the active leaf to trigger the automatic retraction mechanism, so it cannot function correctly on a single door.
Q4: Is the stainless steel material suitable for exterior wooden doors?
A: The bolt and striker are made of Stainless Steel 304, which offers excellent corrosion resistance. While suitable for high-humidity environments, please note that the max door size specified (48"×96") typically refers to standard interior or protected exterior wood-composite doors. For fully exposed exterior doors, additional weatherproofing considerations may be needed.
Q5: Does the "Non-handed" feature mean it fits any wooden door?
A: Yes. The Non-handed (Reversible) design means the bolt can be installed on either the left or right side of the door stile, making it universally compatible with both left-hand and right-hand swing doors without modification.
