It depends on the fault: minor issues (loose screws, stuck handles from dirt) can be repaired with cleaning or tightening. For severe faults (cracked handle body, broken internal pins), replacement is safer—TJJ’s window lock handle is designed for easy installation, so clients can swap old handles quickly. Wholesalers can note that TJJ’s durable handles rarely need replacement (thanks to cast iron/steel construction), but offering bulk replacements ensures clients have backups for urgent needs.
Yes— TJJ’s window lock handle comes in multiple sizes (for casement, sliding, and double-hung windows) and mounting styles, fitting most standard window frames. For custom windows, TJJ offers tailored designs (leveraging its casting expertise) to match unique dimensions. Wholesalers can reassure clients that TJJ’s handles integrate seamlessly with existing windows, avoiding the need for frame modifications.
TJJ’s window lock handle uses hot-dip galvanization or powder coating (depending on the model) to create a rust-resistant barrier, unlike basic painted handles that chip and rust quickly. This coating works for both indoor and outdoor windows, even in humid or coastal areas (common in America’s Southeast or European coastal regions). Wholesalers can highlight this to clients in harsh climates, as it reduces maintenance and replacement costs.
Absolutely— TJJ produces both window lock handle and gate single lock box as part of its window/gate accessory lineup, enabling wholesalers to place single bulk orders for both. This streamlines logistics (one shipment instead of two) and reduces costs, making it ideal for construction projects or property management clients needing full security solutions. TJJ’s export network ensures timely delivery to America, Europe, and Africa, aligning with wholesalers’ global client needs.
First, check if the window frame is warped (minor warping can shift alignment)—gently adjust the frame if possible. If the latch itself is misaligned, TJJ’s window lock handle has adjustable latches (small screws on the latch plate) that let clients tweak position. Wholesalers can provide simple alignment guides (shared by TJJ) to clients, avoiding the need for professional help. For severe alignment issues, TJJ’s customer support team can assist with custom latch adjustments.
