This page is for the rims only (and the Day Box Low). If you need a hatch cover go to the Hatch Cover product page.

Kajak-Sport round hatch rims. These ABS plastic rims are for building your own kayak or replacement for broken rims. 

Kayak brands that use Kajak-Sport hatches include: P&H, TideRace, CD, Eddyline, NDK (except the day hatch which uses a Valley kayak rim), Tahe, Rebel, Zegul, Rockpool, and late model fiberglass WS Tempest Pro (not roto-molded Tempests).

The KS Round series hatch rims are available in four sizes, but the 10cm size is so rarely used (sometimes as an access port to rudder mechanism) that you need to call us to special order that one.

The Day Box Low is a kit to add a "4th Hatch" in front of your cockpit. Use a 6" hole saw or a saber-saw to cut the hole in the deck for the box (kayak deck must have a flat spot of that diameter). Assemble by screwing the rim together with the box - "O"-rings make a seal. Day Box uses a 15cm hatch cover - not included. Most newer P&H Sea Kayaks come with this box standard.

See images below with the outside dimensions of each of the hatch rims. Note the "15cm" hatch cover fits over a 168mm = 16.8cm outside diameter hatch rim. Similarly a "20cm" hatch cover fits a 209mm = 20.9cm dia. rim., and a "24cm" hatch cover fits a 256mm = 25.6cm dia. rim. You can use any style KS brand hatch cover ("Rubber", "Click-On", etc.) with these rims and Day Box.

Typical uses by size (size is the inside diameter of the hatch rim opening not the lid):

15cm/5.91" "Fourth Hatch" (front day hatch in front of cockpit, AKA "whisky hatch" or "glove-box")
Code: 301320

20cm/7.874" "Day Hatch" (behind cockpit except NDK which use Valley hatch cover as an upgrade to the original NDK lid)
Code: 301520

24cm/9.45" Bow Hatch (and sometimes Rear Hatch on kayaks that have a round rear hatch, e.g. NDK Romany)
Code: 301720

Tip: Whenever a rubber hatch cover is difficult to open or close, wipe a little 303 Protectant on the inside lip of the lid and the outside rim of the hatch on the kayak. This will make it much easier to open and close which will protect your kayak from cracking. Also about twice a year it is good to smear 303 on the outside of the cover as a UV block to extend the life of the lid.
