Get more out of the case you already own by rebuilding the interior, replacing what has worn out, and restoring the seal.
Start with your Seahorse case model number, then choose the accessory category below that matches the part you are replacing or the interior you are building.
Rebuild the Case You Already Own Replace foam that has flattened, dividers that no longer suit the kit, latches that have cracked, or a seal that no longer holds. Match the part to your Seahorse case model and keep the case in service instead of replacing it.

Interiors, Hardware, and Replacement Parts for Seahorse Cases
Two things decide how long a Seahorse case stays useful: what holds the equipment inside it, and the parts that wear. Foam and dividers handle the first. Latches, seals, and handles handle the second, and all three are replaceable rather than reasons to buy another case.
Accessory categories
Shop Seahorse Accessories by Category
Interiors and replacement parts are listed per case model, so have your Seahorse case number to hand before you start. The first categories cover what goes inside the case; the later ones cover the parts that wear out.
A rigid perforated panel that drops into the case and lifts back out, with a full grid of holes for partitioning the interior and holding equipment in place.
Best for: Kit that has to be mounted rather than nested, and layouts you want identical from case to case.
These are the situations that come up most often, and the category that answers each one.
The Foam Is Crushed or Wet
Order a Foam set cut for your case model and start the layout again from fresh pluck layers.
The Kit Keeps Changing
Use Padded Dividers so the compartments move with the equipment instead of being cut for one version of it.
Equipment Has to Be Fixed Down
Use an Organizing Board to mount items in a set position rather than nesting them in a cutout.
Small Items Ride Loose on Top
Add a Lid Organizer so leads and paperwork live in the lid where you can see them.
A Latch Has Broken
Fit new Latches and Locks rather than replacing a case whose shell is still sound.
Water Got Into the Case
Replace the Perimeter Seal, which is the part that wears and the usual reason a sealed case stops sealing.
Selection guide
How to Choose a Seahorse Accessory
Start With the Case Number
Foam sets, dividers, boards, and seals are cut for one model, and a case of similar size is not a substitute. Check the number on the case before ordering anything on this page.
Treat the Seal as a Wear Part
A waterproof rating describes a case with a good gasket. Seals take a permanent set from being stored latched, and grit in the groove cuts them. Inspect the seal at the same interval you inspect the gear inside.
Ask How Often the Layout Changes
Foam is cheap and permanent once plucked. Dividers cost more and move freely. If the equipment list has changed twice in the past year, dividers usually work out cheaper than buying foam again.
Measure Your Tallest Item
Depth is the constraint people miss. Check your deepest piece of equipment against the usable depth of the base, especially if a lid organizer or tray is going in above it.
Dry Fit Before You Pluck
Lay the equipment in the open case and mark the layout before removing a single cube. Plucked foam does not go back, and a rushed layout is the main reason a foam set gets replaced early.
Keep Spares for a Fleet
Latches and handles are the parts that fail first in a working fleet. A small stock of both keeps a case in service instead of out of rotation waiting on an order.
Case model decides what fits. How often your kit changes decides which interior is worth paying for.
Seahorse Accessory FAQs
The questions that come up most when people are outfitting or repairing a Seahorse case.
Foam, padded dividers, or an organizing board: which interior should I choose?
Foam gives the tightest fit for the least money, and every item sits in a cutout shaped for it, but the layout is permanent once plucked. Padded dividers cost more, cushion an item on every face, and let you rebuild compartments whenever the kit changes. An organizing board suits equipment that should be fixed in position rather than nested, which is the usual answer for instruments, mounts, and anything you want secured the same way in every case. The deciding questions are how settled the equipment list is and whether the items want to be cradled or held down.
How do I know the perimeter seal needs replacing?
Run a finger around the gasket and look for flattened sections that no longer spring back, nicks or splits, hardening, or grit packed into the groove. A seal that has been stored latched for long periods takes a permanent set, and a flattened seal no longer closes the gap it was designed to close. Any of those, or water appearing inside a case that used to stay dry, means a new seal rather than a new case. Seals are model-specific, so order against the case number rather than by eye.
Can I fit a replacement latch myself?
Yes, latch replacement is a normal field repair rather than a factory job, and the kits come with the parts needed to swap one out. Order against your case model, since latch geometry varies across the range. If several cases in a fleet are on their original latches, it is usually worth ordering spares in one go rather than one at a time as they fail.
Do keyed latches make the case secure?
They raise the effort required rather than making a case secure. A keyed latch stops a case being opened casually, keeps a lid shut in transit, and makes tampering obvious, which is often all that is needed for a case moving between people. It is not protection against a determined attempt on high-value contents. If that is the requirement, tell us what is in the case and how it travels and we can talk through the options.
Will a lid organizer or tray stop my case closing?
It can, and it is the most common reason lid storage gets returned. Measure the loaded height of what sits in the base, then compare the clearance left against the depth of the organizer when it is packed rather than empty. Cases with full-depth foam or tall equipment often have little usable lid volume. A lid that presses down on the contents also loads the seal unevenly, which matters more on a case you need to stay watertight. Send us your case model and what is in the base if the numbers look close.
Can Specialty Cases help me specify an interior?
Yes. Send your case model number, the dimensions and weights of what you need to pack, and how often the kit changes. We can recommend an interior, flag anything that will not clear on depth, and price it across a fleet if you are outfitting more than one case. If no stock set suits the equipment, we can quote foam cut to your own layout instead.

Foam
Lid, base, and pluck layers cut for one case model.
The kit is fixed, or the existing foam is worn out.
A case protects only as well as its interior. Items that shift against each other in transit are the ones that come out damaged.
A Seal You Can Rely On
Checking and replacing the gasket is what keeps a waterproof rating true years after the case was bought.
A Case Kept In Service
A latch, a handle, or a seal costs a fraction of a replacement case, and keeps a standardized fleet standardized.
