FIT, REVIEW, PROTECT

A custom lid should follow the tank—not fight it.

Keepr turns your tank profile, measurements, and equipment routes into a lid you can review before it reaches production.

THE KEEPR FIT GUARANTEE

If it doesn't fit, we remake it once at no charge.

Remake shipping is charged separately and paid by the customer.

MEASUREMENT RESPONSIBILITY

You approve the fit before production.

Your lid is made from the measurements and drawings you approve. Measure carefully.

PRODUCTION PROOF

Approve the exact lid before we print it.

Your production drawing shows the lid footprint, section breaks, openings, and measured dimensions generated from your design. You review it before secure checkout.

DETAILS BEFORE YOU DESIGN

Common questions, clearly answered.

How is my lid priced?

The base price is $1.49 multiplied by the printed square inches shown in the builder. Add-ons, shipping, and taxes are calculated separately.

What do I need to measure?

Start with a saved tank profile when one is available, but treat it as a starting point. You confirm your tank's outside dimensions, equipment clearances, and production drawings before we manufacture.

What is the lid made from?

The frame is printed in black PETG and fitted with clear 1/4-inch mesh.

How does the Keepr Fit Guarantee work?

After you approve the production drawings, if the lid still does not fit the same tank, Keepr will remake it once at no charge. You pay remake shipping. Claims must be submitted within 30 days of delivery, and the total dimension change must be 2 inches or less.

How is standard order shipping calculated?

Standard order shipping is not included in printed-area pricing. It is calculated separately at checkout based on the order and destination.
