London Racket Lab

Custom Trapdoors
for your racket.

A Trapdoor is a removable end cap at the base of your racket handle — a small piece you can pop out and replace. Pick your colours, add your initials, a logo or any image. Designed by you, made to fit. Available for Head, Prince, Babolat, Wilson and Yonex rackets.

How it works

Three steps

01

Select your configuration

Pick your frame, choose colours, and add your initials or a vector image.

02

We make it

Every Trapdoor is individually engineered to perfectly match your racket’s original geometry, custom-finished in your selected palette and bespoke design.

03

Fit it and play

Press it into the handle — same fit as the factory original, no glue, no tools. Pull it out and swap it whenever you like.

Compatibility

Will it fit my racket?

Every Trapdoor is modelled on a real factory end cap, so it pushes into the handle the same way the original did.

Tap a brand to see supported models. Cap shapes vary between years, so check yours against the shape in the configurator before ordering.
