Hey Jose, thanks for reaching out. Yes. The Replacement Sealing Strip # TH28VH is compatible with the Thule Force 3 XL Rooftop Cargo Box # TH87SA.
The Force 3 XL uses Thule's PowerClick mounting system, and the # TH28VH sealing strip is designed to replace the rubber sealing strip around the PowerClick mounting openings. You'll need one sealing strip per mounting clamp, so if you're replacing all four, you'll need to order four strips.

Hi Jose. I got this for the thule force XT cargo box and it was an exact replacement. A bit tricky to install but you just have to pop out the old broken one and slide in the new one from one end to the other.
