Product Overview
A Padded Finger Splint with Two Independent Fastening Straps
The FB-03B Aluminum Finger Splint combines a bendable aluminum shell with a foam-lined finger channel and two adjustable fastening straps. Its curved end wraps around the fingertip, while the longer body extends along the finger to provide external stabilization.
Rather than using metal tabs that fold directly around the finger, FB-03B relies on two separate hook-and-loop straps. These can be fastened at different points along the splint, allowing the fit to be adjusted without repeatedly bending the aluminum shell.
The outer aluminum surface has a series of circular openings, and the blue foam lining cushions the areas in contact with the finger. Three available sizes allow the splint length to be selected according to the finger being supported.
FB-03B is intended for finger immobilization and injury protection where a padded, strap-secured splint is appropriate.
Products Key Features

Curved Aluminum Finger Channel
The aluminum body forms a narrow support channel along the finger, with a curved end that surrounds the fingertip. This arrangement helps maintain the finger in a selected position.
Dual Adjustable Fastening Straps
Two separate hook-and-loop straps secure the splint around the finger. The straps can be opened and adjusted without changing the shape of the aluminum support.
Malleable Support Frame
The aluminum shell can be carefully shaped during fitting. This allows the support angle and contact profile to be adapted to the required finger position.
Foam-Padded Interior
A layer of blue foam covers the inner surfaces of the finger channel and curved tip. The padding provides a softer contact surface between the finger and the aluminum.


Perforated Aluminum Surface
Circular holes are distributed along the upper aluminum shell. They form part of the splint's lightweight construction and provide openings through the metal surface.
Three Size Options
The splint is available in S, M and L. Different lengths allow a more appropriate fit for fingers of different sizes rather than relying on a single fixed-length design.
Independent Finger Immobilization
The splint secures one finger without enclosing the palm or wrist. Adjacent fingers remain uncovered, although their use should follow the relevant injury-management instructions.

Certifications & export readiness:
Designed to meet CE, ISO 13485 and FDA regulatory requirements; suitable for global markets (Europe, North America, Middle East, Latin America, Asia).

Application / Usage
FB-03B may be used for:
- Finger joint stabilization
- Selected stable finger fractures
- Finger sprain immobilization
- Distal finger injury protection
- Mallet finger positioning when clinically appropriate
- Selected tendon injury support
- Post-injury finger immobilization
- Clinician-directed finger rehabilitation
Choosing the Correct Immobilization Position
Different finger injuries require different joint positions. A mallet finger injury, for example, generally requires the distal interphalangeal joint to remain extended, while certain volar plate injuries may require a different splint configuration.
FB-03B should therefore be fitted according to the injury and prescribed positioning requirements rather than being treated as a universal solution for all finger injuries.
Description
How the Strap-Secured Aluminum Splint Works
FB-03B consists of three main elements: a shapeable aluminum frame, a foam-lined finger channel and two hook-and-loop retaining straps.
The finger rests between the padded surfaces, with the curved end positioned around the fingertip. The aluminum body is shaped as needed to maintain the selected alignment. Once positioned, the two straps are wrapped around the splint to hold it against the finger.
Unlike the integrated metal retaining tabs used on FB-01, the separate textile straps on FB-03B allow fastening tension to be adjusted without folding additional metal sections against the finger.
The perforated outer shell also makes the aluminum structure visibly different from an unperforated flat finger splint. Together with the three available sizes, these details provide a practical fitting arrangement for different finger immobilization requirements.
Proper fitting is essential. The straps should secure the splint without creating excessive pressure, numbness or changes in finger circulation.
FB-03B is available for OEM and wholesale supply, with labeling and packaging options based on the order requirements.
FAQ
Q: What is FB-03B used for?
A: FB-03B is a padded aluminum finger splint intended to hold a finger in a selected position. It may be used for certain stable fractures, sprains and other injuries where external finger immobilization is prescribed.
Q: How does the splint stay on the finger?
A: Two adjustable hook-and-loop straps wrap around the aluminum support to keep the splint in place. They allow the fastening tension to be adjusted during fitting.
Q: Can the aluminum frame be bent?
A: Yes. The aluminum is malleable and can be carefully shaped to the required position. The correct angle depends on the affected finger joint and injury.
Q: What is the purpose of the foam padding?
A: The foam creates a cushioned interface between the aluminum shell and the finger, reducing direct contact with the metal surface.
Q: Does FB-03B have ventilation holes?
A: Yes. The outer aluminum shell has a series of circular openings. The amount of airflow reaching the skin also depends on the foam lining and the way the splint is fitted.
Q: What is the difference between FB-03B and FB-01?
A: Both use aluminum and foam padding. FB-03B has two separate hook-and-loop fastening straps and a perforated upper shell, while FB-01 uses integrated bendable aluminum retaining tabs. Their fastening structures are different.
Q: Can FB-03B be used for mallet finger?
A: It may be suitable when the splint can maintain the required fingertip joint extension. A healthcare professional should determine whether its length and configuration are appropriate.
Q: Is FB-03B suitable for a volar plate injury?
A: Not automatically. Some volar plate injuries require a specific degree of joint flexion or an extension-block splint. FB-03B should only be selected when its structure can meet the prescribed positioning requirements.
Q: What sizes are available?
A: FB-03B is available in S, M and L. The appropriate size should be selected according to finger dimensions and the area requiring support.
Q: Does BOSEGROW provide OEM customization?
A: Yes. Custom labeling, packaging and product branding options are available for wholesale and private-label orders.
