To the members of our Mockingbird family:
Mockingbird was founded with the mission to support you through parenthood
every step of the way and offer safe, well-designed, high-quality baby gear
products. We’re thankful to have been made aware of a rare issue some
customers experienced with their Single-to-Double Stroller, and we appreciate
you requesting a Frame Reinforcement Kit so we can help make your strolls even
safer.
The Frame Reinforcement Kit includes two clamps that attach to your stroller frame and help prevent this issue from being able to occur. They have undergone extensive 3rd party testing, and have been reviewed and approved by the U.S. Consumer Product Safety Commission. We know how disruptive it may have been to stop using your stroller while your Kit was on its way, and we greatly appreciate your understanding and patience. If you have any questions as you install it, our Customer Experience Team is here to help – just email us at kit.setup@hellomockingbird.com.
With love,
The Mockingbird Team.
First, unpack the box and make sure you’ve got everything

Prepare your stroller
Engage the foot brake
Push down on the brake to lock your stroller in place.
Important!
Before you start, first inspect the lower sides of the stroller frame, between
the front wheels and the black circular joint (with the Mockingbird logo). If
you see any visible cracks, please stop and contact our Customer Experience
team for the next steps.
Remove the seat(s)
If you have any seats or attachments, push the white buttons on both sides of
the seat(s) and pull up to fully remove them.
Attach the Frame Clamps
Position and align the Frame Clamp
Position the Frame Clamp so that the side with two open holes is on the
outside of the stroller frame. Align the Frame Clamp over the lower frame post
just below the black circular joint (that’s the circle with the Mockingbird
logo on it) so it straddles the black bracket on the frame as shown.
Attach the first Frame Clamp
Apply heavy pressure with your palm to attach the Frame Clamp onto the frame
(it may take some force to attach). The Frame Clamp “CLICKS” on both sides
once it’s in the correct position.
Repeat on the other side
Align the second Frame Clamp over the lower post on the opposite side of the
frame in the same area. Apply pressure until the Frame Clamp “CLICKS”.
Important!
Once the Frame Clamps are attached to the stroller, they are not meant to be
removed.
Add the Bolts
Insert the Bolts
Insert two Bolts into each Frame Clamp so that the Bolts are lined up with the
two openings on the opposite side of the Frame Clamp.
Tighten the Bolts
Tighten each Bolt with the provided Allen Key by turning clockwise until the
Bolt is unable to be turned further. The Bolt should be snug and flush with
the exterior of the Clamp without any visible gaps. You should not be able to
wiggle the Bolt. Repeat with the second Bolt on the Frame Clamp.
Repeat on the Other Side
Repeat the process on the other side of the frame.
Done!
All set, you’re ready to stroll!
Pro Tip
The stroller can still be folded with the Clamps attached.
