The BirdBlocker BoxClip (BB-BoxClip-50s) is a stainless steel fixing clip designed specifically for solar panels with a box-design frame on the short sides — a construction that has become increasingly common among leading panel manufacturers since 2021, replacing the traditional flanged frame. Where standard BirdBlocker clips remain compatible with flanged long sides, the BoxClip was engineered to grip securely onto these newer boxed profile short edges.
Manufactured from high-quality stainless steel, 1.75mm thick, each pack contains 50 clips and is available in two heights (30mm and 35mm) and two frame widths (8–13mm and 14–18mm) to match your specific panel's datasheet dimensions — see the variant table below to select the correct combination for your installation.

Confirm Your Frame Dimensions First
Always check your solar panel manufacturer's datasheet to confirm the exact frame depth and width before ordering. Fitting the wrong height or width variant will result in a loose or ineffective fix. This listing covers the full BB-BoxClip-50s range — see the variant table below for the available height and width combinations.
Installation Note — Narrow Frame Widths
For the narrower 8–13mm and 14–18mm width clips, the frame profile leaves very little clearance. It is recommended that four triangular segments are cut out of the BirdBlocker backstrip at each clip position to allow the clip to seat correctly against the narrow frame. Install a minimum of 4 clips per 50cm of BirdBlocker strip.
Key Features
Purpose-Built for Box-Design Frames
Developed specifically to address the industry-wide shift from flanged panel frames to boxed profiles on the short sides, ensuring the BirdBlocker system stays compatible with modern panel designs where standard clips will not fit.
High-Quality Stainless Steel Construction
Made from stainless steel, 1.75mm thick, chosen for long-lasting durability and strong resistance to rust and corrosion in an outdoor rooftop environment.
Four Size Combinations to Match Any Panel
Available in 30mm or 35mm heights and 8–13mm or 14–18mm widths, covering the vast majority of box-design frame dimensions used by current panel manufacturers.
Secures the BirdBlocker Anti-Nesting Strip
The clip mounts the BirdBlocker strip beneath the solar panel, holding the needle/finger barrier tightly against the roofline so birds cannot access the space underneath.
No Drilling — Warranty-Safe
Clips grip the frame profile directly with no drilling into the panel, so the manufacturer's solar panel warranty is not affected by the bird-proofing installation.
Also Available in Black
Selected BoxClip variants are also available in black to match black-framed panels or black BirdBlocker strips for a more discreet, uniform finish.

Which Variant Is Which
This page covers the full BB-BoxClip-50s family. The bolded rows in the table above correspond to the specific listings requested: 11x35x14-18 (35mm height, 14–18mm width) and 11x30x8-13 (30mm height, 8–13mm width), alongside the standard 11x30x14-18 (30mm height, 14–18mm width) variant. All share identical material, thickness and installation method — only the height and width dimensions differ.
Frequently Asked Questions
How do I know which BoxClip size I need?
Check your solar panel manufacturer's datasheet for the frame profile dimensions on the short side of the panel. You need to match both the height (30mm or 35mm) and the width (8–13mm or 14–18mm) to your panel's box-design frame. If you're unsure, measure the frame directly with calipers before ordering.
What's the difference between the BoxClip and a standard BirdBlocker clip?
Standard BirdBlocker clips are designed for flanged frames with a lip on the underside — the traditional design used by most manufacturers until around 2021. The BoxClip is purpose-built for the newer box-design (boxed profile) frames now used on the short sides of many modern panels, where a standard clip will not grip correctly.
Will fitting this clip affect my solar panel warranty?
No. The BoxClip grips the panel frame profile directly with no drilling or adhesive into the panel itself, so the manufacturer's solar panel warranty is not affected.
Why do I need to cut triangular segments out of the BirdBlocker backstrip?
For the narrower 8–13mm and 14–18mm width variants, the box-design frame leaves very little clearance for the clip to seat against the BirdBlocker strip. Cutting four small triangular segments from the backstrip at each clip position allows the clip to fit correctly without distorting the strip or leaving gaps in the barrier.
How many BoxClips will I need?
Install a minimum of 4 clips per 50cm length of BirdBlocker strip along any box-design frame edge. Calculate the total length of box-design short edges on your array and divide by 0.5m, then multiply by 4, to estimate the number of clips required — then round up to the nearest pack of 50.
Is the BoxClip compatible with both BB125 and BB200 strips?
Yes. The BoxClip is compatible with the full BirdBlocker range, including BB125, BB200, BB125evo and BB200evo strips, wherever the panel's short-side frame uses a box-design (boxed profile) construction rather than a traditional flange.
