The Xit 404 Nauticam Port Cap is a cover that attaches to open end of a macro or wide angle port. This allows you to store other items such as our Manta gears inside when packing for a trip. We suggest that you put some bubble wrap in to protect your port glass first. If you stack your extension rings up and put our Port cap on and a Body Cap on the other end you will have some more storage space when packing for a trip. The cap is made from durable impact resistant Red plastic.
UW Housing Caps are available for a variety of underwater camera housings. Two styles are available to protect your housing body and its ports. Each style of cap is designed to mate with the housing just like the ports do. On the Body Cap is a hot shoe receptacle that secures the sync cable from hanging loose inside the housing. Keep your underwater housing and its sync cable safe with a Body Cap. Use a Port Cap to protect the area your o-ring sits in. You can also put a Body Cap on the other end. That will allow you to utilize that extra space to put say, jelly beans into it.
