Purchasing FAQ
How to choose between hollow and solid U head jack?

-
Free samples are provided, buyers only bear international courier cost. Samples can be shipped within 3 working days together with full set test reports.
What is your minimum order quantity?

MOQ for single in-stock item is 100 sets. Tiered wholesale prices are available for full-container bulk orders. Lower MOQ can be negotiated for long-term cooperative wholesalers.
Can U head jack fit non-standard frame scaffolding?
+
-
Full customization of screw and U tray sizes is supported. Just provide your frame vertical tube drawings, and we will design exclusive customized U head jack solutions for you.
