This Sugatsune kit is the back-to-back mounting kit specified for the DSI-4400-15 door pull. It exists for one purpose: providing the hardware needed to fit a DSI-4400-15 pull on both faces of a door, through-bolted as a matched pair.
A back-to-back installation threads hardware through the full thickness of the door so the two pull halves clamp against each other from opposite faces. That through-bolt arrangement requires a different set of components than a single-face installation, which is why Sugatsune supplies the two configurations as separate kits. This kit is the back-to-back version for the DSI-4400-15 specifically.
The DSI-4400 comes in more than one size, and each size takes its own kit. The size suffix is part of the designation: the DSI-4400-15 and a DSI-4400 at another length are different pulls requiring different kits. Match the full designation on your pull, including the suffix, before placing an order. The single-handle version for this same pull is a separate item as well, so confirm the configuration before ordering.
This kit is the right choice for an architect, installer, or millwork shop fitting DSI-4400-15 pulls back to back, typically on a heavier interior door where a pull is needed from both sides. The DSI-4400-15 pull itself is a separate item and is not included here.
No. This item is the mounting kit only. The DSI-4400-15 pull is a separate purchase.
This kit is for a back-to-back installation, where a pull sits on each face of the door. The single-handle kit fits one pull to one face only. The two are not interchangeable.
No. This kit is specified for the DSI-4400-15. Other sizes in the DSI-4400 range take their own kits.
When a DSI-4400-15 pull is going in back to back, this is the kit that completes the installation.
