Review: 結局これに戻った。 - シャーラーのロックピン等様々試しましたが、結局コレに戻りました。 オリジナルのピンを維持したままにできるのは良い。 シャーラーロックピン等金属製のものは金属が擦れる音が鳴るので、それが気になっていた。 で、結局コレに帰ってきた。 安いし、ギターを多く持ってる人、ビンテージ保有している方にはお勧めできるのではないだろうか。 Review: 引っ張るところが付いているのが良い - 以前から使っていたものが、経年劣化でひび割れてきたので、購入しました。 他のメーカのですと円形ですが、ダダリオのですと、引っ張るところが付いていて、そこをつかんで、 グッと力を入れて引き延ばせるので、取り付けは簡単です。 他社の円形の物とそんなに値段も変わらないのでお勧めです。 ## Features - Flex Lock Strap Blocks is a hassle free strap lock system designed for players who don't want to modify their existing end pins - Simply slip over your existing strap button and you're ready to go - Made of flexible, durable rubber that fits most manufacturers end pins on the market - The design, color, and specifications may change without prior notice due to changes in design on the manufacturer side - This product is a Japanese agent product (parallel import goods cannot be covered by the agent warranty) ## Technical Specifications | Specification | Value | |---------------|-------| | Body Material | ゴム | | Item model number | PW-FLSB-04BK | | Color Name | Black | | Material Type | ゴム。 | ## Images ![D'Addario PW-FLSB-04BK Strap Lock, Flex Lock Strap Blocks, Black, Pack of 4 - Image 1](https://m.media-amazon.com/images/I/61s+R59XfkL.jpg) ![D'Addario PW-FLSB-04BK Strap Lock, Flex Lock Strap Blocks, Black, Pack of 4 - Image 2](https://m.media-amazon.com/images/I/71oZPZoSJoL.jpg) ![D'Addario PW-FLSB-04BK Strap Lock, Flex Lock Strap Blocks, Black, Pack of 4 - Image 3](https://m.media-amazon.com/images/I/81CKFgf4XrL.jpg) ![D'Addario PW-FLSB-04BK Strap Lock, Flex Lock Strap Blocks, Black, Pack of 4 - Image 4](https://m.media-amazon.com/images/I/51i2uH9bVkL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 結局これに戻った。 *by M***A on December 2, 2025* シャーラーのロックピン等様々試しましたが、結局コレに戻りました。 オリジナルのピンを維持したままにできるのは良い。 シャーラーロックピン等金属製のものは金属が擦れる音が鳴るので、それが気になっていた。 で、結局コレに帰ってきた。 安いし、ギターを多く持ってる人、ビンテージ保有している方にはお勧めできるのではないだろうか。 ### ⭐⭐⭐⭐⭐ 引っ張るところが付いているのが良い *by B***G on December 11, 2025* 以前から使っていたものが、経年劣化でひび割れてきたので、購入しました。 他のメーカのですと円形ですが、ダダリオのですと、引っ張るところが付いていて、そこをつかんで、 グッと力を入れて引き延ばせるので、取り付けは簡単です。 他社の円形の物とそんなに値段も変わらないのでお勧めです。 ### ⭐⭐⭐⭐⭐ 安全です。 *by T***I on October 29, 2025* 安いし便利です。取り付けた方が安全です。 ## Frequently Bought Together - D'Addario Flex Lock Strap Blocks - Locks Straps In Place - Protect Your Instrument with No Modifications or Hardware - Easy to Attach - Set of 4 Blocks - Black - D'Addario Dual-Lock Guitar Strap Lock - Guitar Strap Locks Set - Protect Your Instrument with No Modifications or Hardware - Secures Cables - Easy to Attach - 1 Pair,Black - Ernie Ball Polypro Guitar Strap, Black (P04037) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/733019852-daddario-pw-flsb-04bk-strap-lock-flex-lock-strap-blocks](https://www.desertcart.pl/products/733019852-daddario-pw-flsb-04bk-strap-lock-flex-lock-strap-blocks) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
