🛠️ Handle & Attachment Options
• Cape-only setup: Two D-rings placed 6” apart to attach a service cape
• Add extra D-rings: Need a pull strap and a cape? Let us know where you want your D-rings
• Bunny loops (optional): Add loops and extra shoulder D-rings to secure a guide handle
• Handle types available:
• No handle – clean, minimal design
• Built-in counterbalance handle – sturdy and low movement
• Detachable counterbalance handle attachment points – a great flexible option for dogs needing room under tables or handlers who want the option to attach the handle only when needed
 
Note: Guide handles and detachable counterbalance handles are sold separately.
Counterbalance handles are for light grounding support only — not for moderate or heavy mobility.

⚙️ Hardware Finishes Available
Choose from 5 hardware finishes to suit your style and lifestyle:
1. Stainless Steel – One of our most durable options. Rust-proof, scratch-resistant, and ready for all-weather wear.
(Note: Quick-release buckles and lobster clasps in this option are nickel/chrome plated.)
2. Brass – Equally durable and long-wearing, brass is a classic choice that resists rust and develops a natural patina over time. Ideal for tough conditions and everyday use.
3. Black – Matte black steel hardware with a sleek, modern look. A popular fashion finish that may show signs of wear with heavy use.
4. Rose Gold – A beautiful, soft pink-gold finish for a little extra glam. Best suited for light-to-moderate wear.
5. Multichrome (Rainbow) – Eye-catching and full of colour, this fashion hardware option features a vibrant colour-shift finish. Best enjoyed as a statement piece, as it may wear over time with rough use. 
 
Note: Stainless steel and brass are our most recommended options for strength, durability, and long-term use – perfect for dogs who love the water, mud, or rough play. Fashion finishes like black, rose gold, and multichrome are best suited for more gentle wear.
