90-Degree Support Barcket For R2 Series EM-18FB-ZHC

Q1: When exactly is the EM-18FB-ZHC required instead of a standard connector?

A: The ZHC is essential whenever you are connecting two frames where one is taller than the other. Standard straight or T-connectors rely on matching heights; the ZHC provides the specialized 90-degree bracing needed to secure the shorter frame to the vertical side of the taller frame, preventing any swaying or misalignment.

Q2: How many ZHC brackets should be used per joint?

A: For maximum stability, we recommend using at 1 brackets for every multi-height intersection—one positioned near the top of the shorter frame and one near the bottom. This creates a secure "dual-point" lock that withstands the tension of the SEG fabric.

Q3: Does this bracket work with both R2 PVC and R2 Aluminum frames?

A: Yes. The EM-18FB-ZHC is a precision-machined universal component for the Ultra R2 120mm system. Its dimensions are calibrated to fit the internal tracking of both material types perfectly.

Q4: Will using this bracket create a visible gap between the two lightboxes?

A: No. The ZHC is engineered to pull the frames into a tight "butt-joint." Once the graphics are installed, the fabric edges meet seamlessly, creating a professional, clean transition between the different heights.

Q5: Is this part of the standard R2 starter kit, or a separate purchase?

A: The ZHC is a specialized accessory sold in 10-piece sets. It is a "must-have" for rental houses and exhibition designers who frequently build custom-shaped or stepped-profile 20ft booth solutions.
